Flight bookings made on Cryptorefills are processed through Duffel, an airline distribution and booking platform that holds direct connections with a large number of carriers. When a booking is confirmed on Cryptorefills, Duffel creates the reservation in the airline's reservation system and issues a booking reference. This booking reference is the identifier the airline uses to locate the reservation in its own systems, and it is the correct piece of information to use when checking the booking on the airline's website or managing the reservation through the airline's app.
The Cryptorefills confirmation email contains the Duffel booking reference and should be the first document consulted when checking a booking's status. If this email has not been received, checking the spam or junk folder is the correct first step before drawing any conclusions about whether the booking was created successfully.
A confirmed booking in Duffel's system does not always appear in the airline's own booking management tools immediately. The airline's reservation system synchronises with external booking sources on its own schedule, and on some carriers this can take several hours or, in a small number of cases, up to 24 hours. During this interval the booking is genuine and confirmed in Duffel's records, but a search on the airline's website using the booking reference may return a "not found" result or a partially populated record. This is a known delay in the system synchronisation process and it does not indicate that the booking was unsuccessful.
The Cryptorefills confirmation email and the booking reference it contains are the authoritative record of the booking during this interval. Presenting the confirmation email at the airport or check-in desk, together with the booking reference, is sufficient to establish the reservation if the airline's system has not yet updated. Airline staff have access to booking system tools that may show the reservation even when the passenger-facing website does not.
The highest-risk response to a booking that is not immediately visible on the airline's website is to make a second booking on the assumption that the first one failed. A second booking on the same flight creates two confirmed reservations, which typically cannot both be used, and cancelling one of them may involve fees depending on the fare type. The financial and logistical cost of resolving a double-booking is considerably greater than checking with support first.
Before taking any action that creates a new booking, contact Cryptorefills support with the booking reference from the confirmation email and confirm the status of the original booking. Support can verify whether the booking exists in Duffel's system and whether the airline's synchronisation is simply delayed. The guide on booking flights with crypto covers the full booking flow and what the confirmation email should contain.
