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 (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.
- Is it cheaper to book flights months in advance?
- Not much. Booking 2–3 months ahead cost on average 21% more than the same flight's lowest fare, more than at 1.5–2 months (+16.3%). On 29,800 flights seen both 2–3 months and 3–4 weeks out, the early fare was higher 44.8% of the time: a coin toss.
- 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.
