Don’t bother.

Thank you for your feedback and we're sorry to hear that we couldn't help you get upgraded. When our airline partners share the information that a particular flight is already full or even overbooked, that auction does not open, as we strive to provide the best user experience possible. SeatBoost is GDPR compliant and the concerns expressed in this review are not valid. We weren't able to locate any contact with our Customer Service team, but we would be happy to assist you, so please reach out to us directly. As described in our app, please note that the number of last minute upgrades available in a SeatBoost auction can always increase or decrease due to reasons like last minute bookings and “no shows”. We encourage fliers interested in an upgrade to bid in an auction, because there’s always a chance to win, and there’s no cost to participate. Availability can also depend on a number of other factors and the discretion or requirements of the airline. An open seat on the airplane does not guarantee that seat is available for purchase through SeatBoost. That said, because availability can change, we cannot guarantee availability on any flight.
Horrible, Buggy, Waste of Time
