Compare
Run one metasearch to see every seller’s price — never book on the first site you land on.
Stay flexible
Check a day or two either side, and nearby airports. Flexibility beats every “secret” hack.
Set an alert
Track your route and let the price drop come to you instead of refreshing daily.
Book in the window
Roughly 1–3 months ahead for domestic, 2–6 for international. Then book with the cheapest seller.

FAQ
Flights: quick answers
What is the best website to find cheap flights?
Start with a metasearch like Aviasales to compare prices across many agencies and airlines in one search, then book with the cheapest. Cross-check free tools such as Google Flights or Skyscanner, and try Kiwi.com for creative self-transfer routings. Our cheap-flights guide walks through each one.
When is the cheapest time to book flights?
Book domestic trips roughly 1–3 months ahead and international trips about 2–6 months ahead. There is no single magic day to buy — your booking window and flexibility matter far more. Mid-week departures (Tuesday and Wednesday) plus Saturday are often the cheapest days to fly.
Are flight comparison sites free to use?
Yes. Metasearch and comparison tools are free — they earn from the airlines and agencies, not from you. There is usually no booking fee on the search itself; you pay the seller’s price when you book.
Is it cheaper to book flights directly with the airline?
Not always. Online agencies often undercut the airline’s own price, while booking direct can make changes and refunds easier. The smart move is to compare both on a metasearch, then decide whether the saving is worth booking through an agency.
Does TrekQuill earn money from these links?
Yes — some links are affiliate links, so if you book through them we may earn a commission at no extra cost to you. It keeps our guides free. We only recommend tools we’d use ourselves and flag the free options too.
