Note: Most online travel agencies (OTAs) offer similar prices so it’s hard to pinpoint one OTA as the provider of the cheap flight tickets. OTAs are also good at displaying prices for individual flights but do not fare as well when it comes to comparing flight fare options (i.e. economy vs business) on that flight. Check OTA prices against the airline’s own website to ensure you’re getting the best price for your flights.


Agoda works as an OTA and is different from other flight booking sites in that it does not overload users with information on the homepage. The Agoda interface is simple and uncluttered, which makes browsing easy.

Pros and Cons of Agoda


  1. Multilingual
  2. Multiple currencies
  3. Free cancellation within 24 hours of booking
  4. Provides multilingual 24/7 customer support.
  5. Trend window for predictions on prices for flights to the selected destination.


  1. Customer support: Users select a generic type of request from a drop-down list of options. For specific requests through email, an account must be created. No live chat function.
  2. Interface is not very user-friendly as it requires you to mouseover each flight to view if baggage is included or not.
  3. Does not have a flexible dates tool.


Another OTA that offers a quick and easy way to compare flights, Booking.com offers a clean user experience, listing different flight options based on price, time, and carrier.

Pros and Cons of Booking.com


  1. Multilingual
  2. Multiple currencies
  3. Flexibility in customising flights. Users are able to filter their searches by the number of stops, take-off and landing times, airlines, preferred airport, air craft, and flight quality.
  4. Trend window for predictions on prices for flights to the selected destination. This window helps to advise the user on whether to purchase the flight now or wait, based on their prediction of when fare prices will increase.
  5. Provides multilingual 24/7 customer support.


  1. Does not have a rewards programme. Signing up for an account only gives access to members-only pricing and newsletters with discount offers.
  2. Does not have a flexible dates tool.


Expedia is an OTA that offers hotels, flights, car rentals and activities all in one site. On top of its competitive pricing, Expedia offers additional discounts when you book packages through their site. However, do take note that though Expedia ranks highly for its hotel bookings, it isn’t always the cheapest for flight-only deals.

Pros and Cons of Expedia


  1. Expedia Rewards
  2. With the best price guarantee, Expedia promises to reduce their price to lower than the lowest price you can find. Find the exact same deal from other operators at a lower price in order to get a lower price in return from Expedia.
  3. Expedia does not charge a booking fee on round-trip flights on the same airline.
  4. It is one of the only travel booking websites that has a dedicated “Last Minute Deal” page, where you can find last minute flights and hotels on Expedia without breaking the bank.
  5. Transparency of air fares. After selecting your fare, Expedia displays what is and isn’t covered in the fare, including seat selection, cancellations, changes, and baggage rules.


  1. The earning potential on Expedia Rewards through flights is unimpressive and you might be limiting the use of mileage earned toward obtaining and maintaining an elite status. Eligibility for upgrades might also be limited.
  2. No live chat. Customer support is only through email and calls on their toll-free line.
  3. Changes or cancellations to flights are dependent on the airline’s policy and often have to be done directly with the airline.
  4. Expedia’s best price guarantee only works if you find the EXACT SAME deal on another website . You are not eligible for a price reduction or refund if the other deal has a single detail that is different.


Skyscanner is a travel search engine that does not sell flights directly and is particularly useful for travelers with great flexibility on travel dates and destinations. Listed flights are linked to the airline’s website or an OTA to complete the purchase.

Pros and Cons of Skyscanner


  1. Multilingual
  2. Multiple currencies
  3. Price alert function allows you to be notified via email when flight prices drops or rises, keeping you informed on the best times at which to book your ticket.
  4. ‘Everywhere’ search function allows you to travel to anywhere in the world on your preferred dates. The cheapest destination is listed first.
  5. ‘Cheapest Month’ search function shows you the best months to fly to your dream destination. Switch to Chart View to get a bird’s eye view of the prices across the entire month!
  6. Visiting a country for a particular festival or season? ‘Cheapest day of the month’ shows you (in green) which day has the lowest price.


  1. Prices displayed on Skyscanner are not always accurate, as price updates are only reflected after you are transferred to the relevant airline or travel agent to complete the booking.
  2. As bookings are not managed on the site, there is no customer support function. They do, however, provide a help desk for comments and feedback, but this can only be done through email.


Travelocity is owned by the Expedia Group, so flight prices are similar to that of Expedia’s.

Pros and Cons of Travelocity


  1. Price match guarantee: If you find a lower price on an identical itinerary within 24 hours, Travelocity will refund the difference in price plus give you a $50 credit to use on a future booking.
  1. Travelocity Bargain Fares
  2. Free cancellation on flights within 24 hours of booking (on most airlines)
  3. All flight itineraries have ratings with scores out of 10 and ranges from ‘Poor’ to ‘Very Good’. These are assessed based on the duration, type of aircraft, and quality of the amenities available onboard.
  4. Round-trip flights on the same airline do not have booking fee charges.


  1. Travelocity sometimes charges a booking fee.
  2. Does not support a flexible-dates search.
  3. Baggage fees are shown through a drop-down bar, which makes it a little cumbersome to compare fees.


Kayak is an aggregator for travel sites, helping to compare flight prices from many different websites so as to give you the cheapest options available. Their site offers a clean layout creating a good user experience to book and make travel arrangements.

Pros and Cons of KAYAK


  1. Multilingual
  2. Multiple currencies
  3. Kayak hacker fares put together 2 one-way tickets instead of giving a round-trip on 1 airline. This isn’t often found on other websites and could save potentially save you money compared to other similar itineraries.
  4. Fare alerts to track your flight prices.
  5. Wide range of filters and sorting options to customise your flight itinerary.
  6. Allows comparison of your search with other travel search engines.
  7. ‘Flexible dates’, ‘flexible weekend’, and ‘flexible month’ allows you to compare the costs and flights available to get the cheapest days to travel.
  8. Great for researching the best times to travel. Tools on Kayak, like Price Graph, can provide information pertaining to price fluctuations, making it easy for users to find cheap tickets for travel.


  1. No direct bookings means greater hassle as you will be redirected to the airline’s website or OTA to purchase your flight. Booking one of Kayak’s hacker fares would thus mean having to go to two separate websites to complete the booking.

Book a flight or a package?

Most travel sites offer better deals with their packages, so if you need to make multiple bookings for flights, hotels and activities, it is worth seeing what discounts you can get for bundling through a travel site. If you are only looking at flights, it might be best to book with the airline directly, after using these travel sites for comparison.
