Booking tips from our fare data

How far in advance should you book a flight?
Book 1.5–2 months before departure. Tracking the same flights at every lead time (113,810 flights on 22,061 routes, 2026-06-14 to 2026-11-11), that window had the smallest average premium over each flight's lowest fare: +16.2%, against +48.7% in the last 3 days.
Is it cheaper to book flights months in advance?
Not much. Booking 2–3 months ahead cost on average 20.9% more than the same flight's lowest fare, more than at 1.5–2 months (+16.2%). On 30,555 flights seen both 2–3 months and 3–4 weeks out, the early fare was higher 44.7% of the time: a coin toss.
Are flights getting more expensive?
Not right now. The Piratefly monthly Fare Index stands at 98.7 in 2026-11 (month in progress), against 100 in 2026-08: comparable flights are 1.3% cheaper than then, measured on the same routes month to month.
