Booking tips from our fare data

Book 1.5–2 months before departure. Tracking the same flights at every lead time (110,945 flights on 21,717 routes, 2026-06-14 to 2026-11-10), that window had the smallest average premium over each flight's lowest fare: +16.3%, against +48.8% in the last 3 days.
Are flights getting more expensive?
Not right now. The Piratefly monthly Fare Index stands at 98.5 in 2026-11 (month in progress), against 100 in 2026-08: comparable flights are 1.5% cheaper than then, measured on the same routes month to month.
What is the cheapest day of the week to fly?
Wednesday. Comparing each fare with the median of its own route, Wednesday departures were +3.9% and Tuesday +4.2%, while Friday was the dearest at +10.4%. Weekend departures cost more than midweek ones.
