Question 1

Is Kayak or Priceline better for finding cheap flights?

Accepted Answer

For research, Kayak is better — its metasearch surfaces the cheapest fare across hundreds of airlines and OTAs, and its filters (layover length, cabin, hacker fares) beat Priceline's for finding edge-case cheap itineraries. For actually booking a cheap flight, Priceline can win on specific routes because of its Express Deals opaque product, which discounts 20–40% by hiding the airline until purchase, and its flight + hotel bundle discounts. The catch with Kayak is that once you click 'book,' you're handed off to a partner OTA whose service fee, change policy, and support quality vary widely. CheapoTrav typically beats both on final all-in price because it charges $0 booking fees, pulls agent-only unpublished fares, and books on-platform with a single accountable party.

Question 2

Is Kayak actually a booking site or just a metasearch?

Accepted Answer

Kayak is a metasearch, not a booking site — it aggregates flight and hotel prices from hundreds of airlines and OTAs, then redirects you to whichever partner has the lowest price to complete the transaction. That means the price you see on Kayak isn't always the price you pay: the partner OTA can add a service fee, a change fee schedule, or a fare rule at checkout. Priceline, by contrast, is a booking site — it's the merchant of record on tickets sold through priceline.com, so the price you see is closer to the price you pay (before taxes and any add-ons).

Question 3

Are Priceline Express Deals real savings?

Accepted Answer

Yes, but with a real trade-off. Express Deals on flights hide the airline (and sometimes exact departure time) until after purchase, and the savings are typically 20–40% off the published fare on the same route. They're worth it when the route is short, the flexibility loss is acceptable, and you don't have elite status you're trying to protect. They're not worth it when you need a specific carrier for elite qualifying credit, when award mileage matters, or when you might need to change or cancel — Express Deals are non-refundable and change fees are harsh.

Question 4

Which is cheaper for international flights, Kayak or Priceline?

Accepted Answer

For most international itineraries, Kayak wins on transparency and price discovery because it can surface fares from foreign OTAs and hacker-fare combinations (two one-ways on different carriers) that Priceline's booking engine won't build. Priceline can win when it has private international inventory in Express Deals or when a bundle discount stacks on a package trip. On premium-cabin international, both are typically beaten by CheapoTrav's phone desk, which has access to consolidator fares that don't appear on any public site.

Question 5

Does Kayak charge booking fees?

Accepted Answer

Kayak itself doesn't charge a booking fee — it's a metasearch that makes money from partner referrals. But because Kayak redirects you to a third-party OTA to complete the booking, any fees that partner charges (service fee, phone-agent fee, non-refundable change fee) still hit your final total. That's the hidden cost of Kayak: the price on the search results page is not always the price at the partner's checkout. CheapoTrav shows the total price upfront and charges $0 booking fees on every reservation.

Question 6

Is Priceline safe to book flights on?

Accepted Answer

Yes. Priceline is a publicly traded subsidiary of Booking Holdings (the same parent as Booking.com, Kayak, and Agoda) and is the merchant of record on tickets it sells on-platform. The main risk with Priceline isn't safety — it's inflexibility: Express Deals and Name Your Own Price flight bookings are non-refundable and non-changeable, and standard Priceline tickets go through Priceline support rather than the airline for changes and IRROPS.
