Our Testing Methodology: Finding the Best Airline Travel Sites
To provide you with the most reliable recommendations for best airline travel sites, we conducted extensive testing across 15 platforms, evaluating them on 32 different flight itineraries. Our tests included a mix of last-minute flights (departing within a week) and advance purchase fares (booked three months ahead), known as APEX fares.
We strategically selected a range of routes, encompassing major international gateways such as New York City (NYC) to Los Angeles (LAX), LAX to Hong Kong (HKG), and NYC to Paris (CDG). We also included secondary routes like Philadelphia (PHL) to Tampa (TPA), Chicago (CHI) to Rome (FCO), and Miami (MIA) to Rio de Janeiro (GIG) to assess performance across diverse destinations. To further challenge the sites, we incorporated a long-haul “curveball” route from Dallas (DAL) to Dubai (DXB) and a European route without North American legs, London (LON) to Barcelona (BCN), to evaluate their handling of low-cost carriers prevalent in Europe.
Crucially, we prioritized realistic and practical flight options. We disregarded artificially low fares that came with excessively long layovers, multiple stops, or convoluted routing that significantly increased travel time. Specifically, we rejected any itinerary that extended the total travel duration by more than 50%. While some airlines might consider these options viable, we focused on efficient and reasonable travel plans for our readers seeking the best airline travel sites.
Our scoring system was meticulously designed to objectively rank the best airline travel sites. We awarded points based on fare competitiveness: three points for finding the lowest fare, two points for the second lowest, and so on. Conversely, we penalized sites with negative points if their fares were higher than the average fare found across all tested platforms. To account for minor price variations, fares within 1% of each other were considered equivalent. This rigorous, weighted system ensured a fair and data-driven ranking of the best airline travel sites for 2024.

Key Considerations When Using Airline Travel Sites
Before diving into our top picks for the best airline travel sites, it’s important to understand some fundamental aspects of how these platforms operate and what to watch out for when searching for flights.
Aggregators vs. Online Travel Agencies (OTAs)
Understanding the difference between aggregators and OTAs is crucial for navigating the world of best airline travel sites.
-
Aggregators: These sites act as search engines, scanning numerous booking engines, airfare websites, and OTAs to compile flight results in one place. They don’t sell tickets directly. Instead, when you find a flight you like, you’re redirected to the third-party site (OTA or airline) to complete the purchase. Think of them as comparison tools for best airline travel sites.
-
Online Travel Agencies (OTAs): OTAs, on the other hand, are booking engines that directly sell flight tickets (and often hotels, car rentals, etc.). Examples include Hotwire, Kiwi, and CheapOAir. They source fares from airlines and may also participate in aggregator searches.
The quality of an aggregator largely depends on the OTAs and sources it includes in its search. Reputable aggregators strive to filter out unreliable ticket sellers, but it’s always wise to exercise caution when dealing with unfamiliar companies. Whenever you are redirected to a new booking site from an aggregator, especially one you haven’t used before, it’s recommended to perform a quick check with the Better Business Bureau (BBB.org) to look for any complaints or red flags. This extra step ensures you are booking through a trustworthy platform, even when using the best airline travel sites.
Beware of Misleading Practices
Some less scrupulous OTAs may employ tactics that can be misleading. Be aware of these potential issues when using airline travel sites:
-
Bait-and-Switch Pricing: Some OTAs might advertise very low “lead prices” initially, only for the actual price to increase once you click through to book. This can be frustrating and time-consuming.
-
“Direct” vs. “Nonstop” Flights: Be cautious of the terms “direct” and “nonstop.” “Nonstop” means the flight goes directly from origin to destination without stopping. “Direct” flights, however, may make stops but don’t require you to change planes. Some OTAs might misleadingly categorize direct flights as nonstop. Always double-check the flight details to confirm whether it’s truly nonstop if that’s your preference.
-
Price Fluctuations: Airfares are dynamic and can change rapidly, even within moments. While even the most reputable aggregator strives to display accurate prices, you might occasionally be redirected to a site where the initially quoted fare is no longer available. If this happens frequently during your search on best airline travel sites, it might indicate an issue with the aggregator or the linked OTA.
Southwest Airlines and Direct Booking
A critical point to remember when searching for flights on best airline travel sites is that Southwest Airlines flights are generally not listed on most third-party OTAs or aggregators. Southwest intentionally restricts its fare distribution, primarily selling tickets directly through its own website, Southwest.com.
There is one exception: Google Flights, which, as of spring 2024, has begun to include Southwest fares in its search results. However, for the most comprehensive search of Southwest flights, it’s still best practice to check Southwest.com directly. Therefore, when comparing fares using best airline travel sites, remember to always check Southwest’s website separately to ensure you’re not missing out on potential deals, especially if Southwest is a preferred airline for your route.

Top 10 Best Airline Travel Sites in 2024: Detailed Reviews
Now, let’s delve into our detailed reviews of the top 10 best airline travel sites for 2024, ranked from #10 to #1.
#10: Google Flights (Aggregator)
Google.com/flights
While Google dominates online search, Google Flights (https://www.google.com/travel/flights) lands at the bottom of our top 10 best airline travel sites. Despite its strengths, its performance in finding the absolute lowest fares was inconsistent.
Pros:
- Speed and Real-time Updates: Google Flights is exceptionally fast, refreshing results instantly as you type destinations or adjust filters.
- Price Calendar: The pop-up calendar displays average prices for each day, making it easy to identify the cheapest dates to fly at a glance.
- Southwest Inclusion: Google Flights is the first major platform to incorporate Southwest Airlines fares into its search results.
- Detailed Filters: Offers comprehensive filters and the ability to include or exclude specific airlines or connecting airports.
- In-flight Amenities: Lists in-flight amenities like legroom, seat outlets, entertainment, and Wi-Fi.
Cons:
- Inconsistent Pricing: Google Flights’ price results were highly variable. While it occasionally found the best fare, it often lagged behind competitors, particularly on major routes.
- Average to Higher Prices: Frequently displayed fares that were slightly (5-15%) to significantly higher than other best airline travel sites for the same flights. In one instance, for a last-minute Dallas-Dubai flight, Google was dramatically more expensive than the top-performing sites.
- Not Optimized for Best Deals: While excellent for finding flight availability and options, Google Flights is not consistently the best choice when price is the primary concern.
Summary: Google Flights is a powerful tool for initial flight research due to its speed and features, but it shouldn’t be your sole source when seeking the absolute lowest fares. It’s best used in conjunction with other best airline travel sites on our list.
Hotwire website interface, representing an OTA among best airline travel sites known for discounted travel deals.
#9: Hotwire (OTA)
Hotwire.com
Hotwire (https://www.hotwire.com/flights/) makes a return to our rankings of best airline travel sites after a hiatus, but with significant caveats. Notably, it should be avoided for last-minute bookings.
Pros:
- Decent APEX Fares: Hotwire performs reasonably well for advance purchase fares, often finding average to slightly below-average rates.
- Lower Direct Flight Prices: Frequently secures lower or even the lowest rates on direct flights when booking in advance.
Cons:
- Terrible Last-Minute Fares: Hotwire performed the worst among all tested sites for last-minute flights, consistently presenting the highest fares.
- Sub-par Filters: Lacks essential filters, including the ability to specify maximum flight time or layover duration, standard features on other best airline travel sites.
- Ignores No-Frills Carriers: Hotwire often misses opportunities to include low-cost carriers in its search results, leading to missed savings.
- Limited Airport Search: Defaults to searching only one airport at a time, missing cheaper flights from nearby alternate airports. This was particularly evident in our London-Barcelona route test, where Hotwire failed to identify significantly cheaper no-frills options available at other London airports.
Summary: Hotwire can be considered for advance purchase fares, particularly for direct flights. However, its poor performance with last-minute fares, limited filters, and tendency to overlook budget airlines make it a less competitive option compared to other best airline travel sites, especially for travelers seeking the absolute lowest prices or flexible options. Its reliance on the Hotwire engine by Expedia, Orbitz, and Travelocity means searching those sites essentially yields the same results as Hotwire.
Hopper app interface on a smartphone, representing a mobile-first aggregator among best airline travel sites with price prediction features.
#8: Hopper (Aggregator)
Hopper.com
Hopper (https://hopper.com), a mobile-first travel app known for its user-friendly interface and price prediction features, drops significantly in our rankings of best airline travel sites this year.
Pros:
- Decent Advance Purchase Fares: Hopper provides reasonably competitive fares for advance bookings, often slightly better than average.
- Price Prediction Advice: Offers advice on whether to book now or wait based on price trends, though this feature is less comprehensive than in the past.
- Color-Coded Calendar: The date selection calendar is color-coded to highlight the cheapest travel days.
- “No Change Fee” Filter: Uniquely offers a filter to limit results to flights with no change fees.
Cons:
- Poor Last-Minute Fares: Performed poorly in the last-minute category, consistently displaying higher prices.
- Limited Filters: Offers a restricted set of sort-by filters compared to other best airline travel sites.
- Aggressive Upselling: Hopper heavily promotes its add-on services like fare freezing and travel insurance, requiring multiple steps to decline them, which can be intrusive.
- Feature Reduction: Has removed previously available features like historical price graphs, baggage fee information, and seat pitch details, reducing its overall utility.
Summary: Hopper can be useful for travelers planning in advance and seeking basic fare comparisons. However, its subpar last-minute fares, limited filters, and aggressive upselling detract from its appeal compared to other best airline travel sites. The reduction in previously helpful features also makes it less informative than it once was.
Kiwi.com website interface, representing an OTA among best airline travel sites known for flexible travel options and bus/train integration.
#7: Kiwi (OTA)
Kiwi.com
Kiwi (https://www.kiwi.com/en/), a Czech-based booking site, also experiences a significant drop in our rankings of best airline travel sites. While not consistently poor, its performance has become less impressive.
Pros:
- Flexible Date Options: Excellent for flexible travelers, with a default “anytime” departure date and price calendars showing fares over two months.
- Fare Grid and Trends: Results page includes a fare grid for nearby dates and a price trend graph.
- Bus and Train Integration: Uniquely includes train and bus options alongside flights, offering comprehensive travel planning.
- Powerful Filters: Features a robust set of filters, second only to our top-ranked site.
- Baggage Fee Inclusion: Can display baggage fees within fares.
Cons:
- Inconsistent Fares: Performance in finding the lowest fares is inconsistent, particularly for advance purchase direct flights.
- Customer Service Concerns: Receives negative reviews and Better Business Bureau complaints regarding customer service when issues arise. Some travelers might prefer to use Kiwi for itinerary planning but book elsewhere due to these concerns.
Summary: Kiwi remains a strong option for travelers with flexible dates or those seeking multi-modal transportation options. Its powerful filters and fare visualization tools are valuable assets. However, inconsistent fare performance and customer service concerns prevent it from ranking higher among best airline travel sites.
Priceline website interface, representing an OTA among best airline travel sites known for "Express Deals" and discounted travel.
#6: Priceline (OTA)
Priceline.com
Priceline (https://www.priceline.com/flights/) makes a comeback to our list of best airline travel sites, improving significantly after previously falling out of the top 10.
Pros:
- Improved Filters: Has significantly enhanced its filter options.
- Price Comparison Calendars: Features daily price comparisons on the date picker calendars.
- Includes Low-Cost Carriers: No longer ignores budget airlines, expanding its fare options.
- Inventive Itineraries: Occasionally identifies creative, lower-cost itineraries, such as suggesting layovers in specific cities to reduce fares.
- “Express Deals”: Offers opaque “Express Deals” where flight details are revealed only after booking, potentially offering discounts (though often closer to 10% than the advertised 40%).
Cons:
- Mediocre Last-Minute Fares: Last-minute fares remain Priceline’s weakness, underperforming even Kiwi.
- Middle-of-the-Road Pricing: Overall price performance is solid but not exceptional, particularly compared to top-ranked best airline travel sites.
- Opaque Fare Uncertainty: “Express Deals” involve uncertainty regarding flight times, airlines, and stopovers, which may not appeal to all travelers.
Summary: Priceline is a much-improved contender among best airline travel sites, offering a balanced performance with decent filters and occasional cost-saving itinerary suggestions. Its “Express Deals” can be worth considering for flexible travelers willing to accept some uncertainty for potential savings. However, its last-minute fares and overall price competitiveness are not top-tier.
Tripadvisor website interface, representing an aggregator among best airline travel sites known for travel reviews and comprehensive travel planning.
#5: Tripadvisor (Aggregator)
Tripadvisor.com
Tripadvisor (https://www.tripadvisor.com/CheapFlightsHome) maintains its position in the middle of our rankings of best airline travel sites, offering consistent but not groundbreaking performance.
Pros:
- Decent Prices: Provides generally competitive fares.
- Good Filters: Offers a fair variety of filters for refining search results.
- Nearby Airport Inclusion: Allows searching for flights including nearby airports, potentially uncovering cheaper options.

- Average Last-Minute Fares: Performance on last-minute fares is consistently average.
- Aggressive Pop-up Windows: Automatically opens search windows for other sites unless this option is deselected, which can be disruptive.
- Questionable Itineraries: Occasionally suggests less desirable itineraries in pursuit of savings, such as flights with very long layovers.
Summary: Tripadvisor is a reliable and familiar option among best airline travel sites, providing decent fares and helpful filters. Its inclusion of nearby airports and trusted booking site filter are valuable features. However, its slower speed, average last-minute fares, and tendency to suggest questionable itineraries prevent it from ranking higher.
CheapOAir website interface, representing an OTA among best airline travel sites known for last-minute flight deals.
#4: CheapOAir (OTA)
CheapOAir.com
CheapOAir (https://www.cheapoair.com/flights/) stands out as the top-ranked OTA on our list of best airline travel sites, particularly excelling in last-minute flight deals.

Summary: CheapOAir is a must-consider website if you’re booking last-minute flights. Its dominance in this area is undeniable. However, its inconsistent performance on advance purchase fares and user experience issues (slow speed, pop-ups) mean it’s not a universally top-ranked best airline travel site. For advance bookings, it’s advisable to compare CheapOAir’s fares with our top three recommendations.
Skiplagged website interface, representing an aggregator among best airline travel sites known for hidden city fares and direct flight deals.
#3: Skiplagged (Aggregator)
Skiplagged.com
Skiplagged (https://skiplagged.com), a relatively newer aggregator, enters our top three best airline travel sites due to its strong performance, particularly on direct flights and user-friendly interface.
Pros:

Summary: Skiplagged is a strong contender among best airline travel sites, especially if you prioritize direct flights and appreciate a fast, intuitive interface. Its price calendar and direct flight performance are standout features. However, its limited filters, lack of baggage fee information, and association with “hidden city” fares (even if optional) are points to consider.
