Skyscanner remains essential as a secondary check because it surfaces OTAs that Google now excludes. Kiwi's self-protected itineraries unlock combinations no one else offers, but its cancellation policies are aggressive enough to warrant caution. Momondo and Kayak are useful price-comparison cross-checks. Most listicles rank by price-found-once; we weight what actually happens at checkout and when things go wrong. **On this page** 1.

The wider OTA coverage occasionally surfaces meaningfully cheaper fares. #### Pros - Surfaces OTAs and low-cost carriers that Google may not list - Strong flexible search and 'cheapest month' tools - Active mobile app with price alerts - Established international reputation #### Cons - Many results route through OTAs — changes and refunds can be slower - Some quoted prices change at the OTA's checkout - Mobile app pushes upsells **Price:** Free aggregator **Sources:** [www.skyscanner.com](https://www.skyscanner.com/) [Visit Skyscanner →](https://skyscanner.com/ "Skyscanner — OTA-inclusive comparison especially for international and low-cost routes") #3 ### [Kiwi.com](https://kiwi.com/) Self-protected combinations of separate airline tickets Use when the route Kiwi finds saves enough money to justify the change-policy risk. Read the policy carefully before booking and consider standalone travel insurance. #### Pros - Combines flights from unrelated airlines into a single itinerary with their own guarantee - Often surfaces routes no other aggregator finds - Strong for budget-airline combinations #### Cons - Cancellation and change policies are aggressive — fees can exceed the original fare - Their guarantee covers missed connections only under their terms - Customer service has been criticized for slow resolution on disputes - Self-protected itineraries are exotic — the airlines themselves do not coordinate them **Price:** OTA pricing with Kiwi protection fee included **Sources:** [www.kiwi.com](https://www.kiwi.com/) [Visit Kiwi.com →](https://kiwi.com/ "Kiwi.com — Self-protected combinations of separate airline tickets") #4 ### [Momondo](https://momondo.com/) Cross-check aggregator with strong design Use as a third opinion after Google Flights and Skyscanner. Same parent as Kayak so results overlap. #### Pros - Clean modern interface for comparison - Owned by Booking Holdings — significant data sourcing under the hood - Strong calendar view for flexible dates #### Cons - Owned by the same parent as Kayak — results often similar - Many results route through OTAs - Mobile-first design that desktop users may find limiting **Price:** Free aggregator **Sources:** [www.momondo.com](https://www.momondo.com/) [Visit Momondo →](https://momondo.com/ "Momondo — Cross-check aggregator with strong design") #5 ### [Kayak](https://kayak.com/) Long-running aggregator with strong filter set Solid third opinion. Use the filters to narrow on specific preferences after running Google Flights and Skyscanner. #### Pros - Comprehensive filter options for layovers, airlines, and times - Hacker fare combinations sometimes save money - Established trust signals #### Cons - Aggressive OTA routing on some results - Pricing not always best in market - Booking Holdings ownership overlap with Momondo and others **Price:** Free aggregator **Sources:** [www.kayak.com](https://www.kayak.com/) [Visit Kayak →](https://kayak.com/ "Kayak — Long-running aggregator with strong filter set") ## How we chose - Price accuracy from search result to checkout — quoted prices that hold or jump. - Coverage of low-cost carriers and OTAs that may not feed major aggregators. - Exploration tools — flexible dates, anywhere search, price trends. - Booking flow — direct to airline versus through an OTA middleman. - Change and cancellation reality — what happens when you need to modify. - Hidden costs disclosure including bag fees and seat selection. ## Frequently asked questions Should I book directly with the airline? Yes when prices are equal. Direct-airline bookings simplify changes, refunds, and irregular operations. OTAs add a layer of customer service that can slow resolution when something goes wrong. Why is the price different at checkout? Aggregators receive cached prices and route to OTAs whose live prices can differ. Google Flights tends to be the most accurate. OTA-heavy results on other sites are more likely to change. Is Kiwi safe? Kiwi operates legitimately, but its self-protected itineraries combine unrelated airline tickets in ways the carriers themselves do not coordinate. Missed connections are covered only under Kiwi's terms. Read the policy carefully and consider travel insurance for higher-value bookings. What about hidden city ticketing? Skiplagged surfaces hidden-city itineraries where you intentionally miss the second leg. Airlines forbid this in their contracts and may cancel return flights or pursue frequent fliers who do it repeatedly. Use with awareness of the risk. When are flights cheapest? Patterns vary by route. Use Google Flights' price trends and calendar view to find the cheapest date for your specific route. The much-quoted 'Tuesday is cheapest' rule does not hold across all routes.
