Flare is a flight-deal alert app for iPhone and Android: it scans fares and flags unusually low prices. Flare is not an airline, not a travel agency and not Flair Airlines. You book with the airline or the provider.

Flare compares each observed fare with the reference price of the same route. A row appears here only when the rounded drop is at least 55% and the source batch is less than 12 hours old. Amounts are shown in euros, the common unit of the public data set.
Before you book
- Open the fare with the provider and check the final payable total, dates and baggage.
- Airlines can cancel or reprice a genuine mistake fare. Do not book non-refundable hotels until the ticket is issued.
- Read the mistake-fare guide for the checks and what airlines usually do.
