Frequently asked questions

No. Tripiefly is an independent travel publication. We don’t sell tickets, take bookings or handle payments. Our guides explain how to find lower fares; you always book directly with the airline or a booking site of your choice.
No. Fares change all the time and depend on dates, seats left and add-on fees. When we mention a price, we say where and when we saw it. Always check the final total, including bags and seat selection, before you pay.
Ads keep Tripiefly free. They come from Google’s ad network and are labeled as Advertisements. After the quiz you can choose to watch one short ad to see your top 3 picks first, or say no thanks and browse every guide in the standard order. If you skip the quiz, all guides stay available.
No. All Tripiefly guides are free to read, with no sign-up.
Often, yes. U.S. rules require airlines to either let you cancel for a full refund or hold the fare without payment for 24 hours, when you book at least seven days before departure. It applies to tickets bought directly from the airline, not from online travel agencies, and each airline chooses which of the two options it offers.
If you decide not to travel or turn down a credit, U.S. rules entitle you to a refund to your original form of payment, issued automatically: within 7 business days for card purchases, 20 days for other payments. A significant change includes departing or arriving 3+ hours off schedule on a domestic trip (6+ hours internationally). U.S. airlines aren’t required to pay cash compensation for delays, but the largest ones commit to meal vouchers and free rebooking when a delay is within their control.
Yes. Booking in the right window, comparing red-eye and early flights, checking nearby airports and avoiding bag fees can all lower the price even when your dates can’t move.
