Date-comparison advice
- Start with September 2026 as the first cached month to recheck, then compare the same trip length in the month before and after it.
- Compare at least 3 covered origins before assuming one departure airport represents the whole London market.
- Move the departure and return dates by one or two days to see whether the cheaper signal is tied to a specific weekday pattern.
- Recheck baggage, seat, refund, and connection rules with the booking provider before treating a low base fare as the best trip.
- For Europe trips, compare shoulder-season weeks against peak summer and late-December windows.
What this page does not guarantee
- It does not show live fares, seat availability, fare rules, baggage fees, or booking-provider inventory.
- It does not prove that September 2026 will be cheapest for every origin or trip length.
- It should be used to shortlist months and date ranges before opening provider search results.
