What the service does

SeatBoost is a no-cost iPhone application that runs live, last-minute auctions for seat upgrades. Bidding opens as early as 24 hours before departure, and you can place offers for upgrades into higher fare classes. You may submit bids for yourself and any companions traveling with you. If your bid succeeds, you are only charged for the upgrade when the auction concludes.

Quick steps to join an auction

  • Auctions become available starting 24 hours before your flight departs.
  • Locate the specific flight you want to upgrade and enter its live auction.
  • Submit bids for yourself and/or your travel companions during the live event.
  • If your bid wins, the charge for the upgrade is processed at the end of the auction.
  • Install the SeatBoost app and confirm your flight is eligible before joining.

Where SeatBoost is usable and future plans

  • SeatBoost currently partners with TAP Air Portugal for upgrade auctions.
  • The team intends to add additional airline partners over time.
  • To receive announcements about new airline integrations, sign up for their mailing list on the SeatBoost website.

Help, contact options, and privacy

  • For questions or assistance, use the contact form available on the SeatBoost website.
  • Details about how personal information is handled and disclosed can be found on the site’s privacy policy page.

Alternative option (paid)

  • If you’re looking for a different utility, consider a paid family GPS phone tracker (often listed as “Family Locator”) as a separate paid service.
