Use aggregators to check airfares on many OTA sites (Online Travel Agencies) simultaneously. My favorites:
Once you have found the flights of your choice, make sure to double check the price on the website of the airline to ensure you are booking at the lowest price. Tip: Verify the price on the local website of the airline. (e.g. the Portuguese website version of a Brazilian airline might offer lower airfares than their English version!) Also keep in mind there might be extra charges for checked luggage, seat selection, credit card payments, etc…
2. Keep track of deals and promotions
Here’s how to keep track of the latest flight deals and promotions:
- Sign-up for newsletters of airlines flying to your favorite destinations
- Monitor frequent flyer forums Flyertalk & Vielvliegertreff
- Follow twitter & facebook accounts of travel deal sites (enable notifications!)
Frequent flyer forums like Flyertalk are generally the first to report amazing travel deals (including error fares). The problem is the format in which the information is published which might be quite challenging for newcomers. Tip: use ITA Airline and Airport Code Search to better understand postings on frequent flyer forums. Note that you can also set email alerts for your preferred threads / sections on those forums. That way you get the latest deals automatically in your mailbox. For even faster notifications, follow travel deal sites on social media and enable push notifications for their Twitter accounts and Facebook pages. e.g SecretFlying on Twitter and Facebook.
