AIRLINE-SANCTIONED SEAT MARKETPLACE

A new revenue stream on the seats you have already sold

Passengers forfeit billions on non-refundable tickets they can't use, while your most in-demand flights depart with no-show seats empty. SeatClear lets one passenger's unusable ticket become another's seat, only on sold-out flights: you set the price band, approve every trade, keep the data, and earn on inventory you had already sold once.

Concept preview: figures are illustrative and any carrier shown is a sample. SeatClear is a software layer and never a payment intermediary.

Five ways a held seat changes hands

All five run only on sold-out flights and non-refundable tickets, inside your price band, gated behind your loyalty program. Sellers recover their fare and can profit; you earn on every transaction.

Buy
Get a seat on a sold-out flight a passenger can no longer use. Reissued in the buyer's name instantly, earning miles like any ticket.
Sell
Can't fly? List the ticket instead of forfeiting it. Price it inside your band and get paid the moment it sells. Sold means paid.
Swap
Trade seats with another passenger on a full flight, for a fee: window for middle, sitting with family, economy to first with the fare difference paid first.
Offer
Want a seat that's taken? Bid on the passenger who holds it. When nothing is listed, offers create the market.
Trade
Switch whole flights on the same route, different departure, when both are sold out. Both tickets reissued together, atomically.

Every trade clears your queue, on rails you own

Nothing moves without the carrier. A trade only appears once a flight is sold out, is priced inside the band you set, and clears your approval before it executes. The buyer pays through your own checkout, the seller is paid on your refund rails, and the ticket is reissued in the buyer's name, earning your miles. You are merchant of record and system of record; no money passes through SeatClear.

A second sale on a seat you already sold

A resale seat is a full airline ticket: reissued instantly, earning miles, and a fresh chance to attach your own extras. When the buyer checks out, SeatClear pulls your live add-on prices, a bag, Wi-Fi, lounge, priority boarding, all optional, all charged by you. Without SeatClear that seat flew empty or with the seller's extras already paid; there was never a second bag sale on it.

You keep control. SeatClear is the software layer.

The airline sets the price band on every flight, approves each transaction, is paid first, processes all money on its own rails, and owns every piece of customer data. The airline-technology layer, PSS and order-management integration, reissue, loyalty hookup, is delivered and operated 24/7 by Branchspace, an airline order-management specialist. Systems access, not capital: no cash outlay, minimal internal work.

WHY AIRLINES SAY YES
  • Money: a commission and reissue fee on every trade, plus a second ancillary sale, on inventory you already exhausted.
  • A post-booking revenue gap closed: value recaptured from no-shows and unmet demand on full flights.
  • Loyalty fuel: access requires membership, premium features track your tiers, and every purchase earns your own points.
  • Zero capital, zero downside: pure revenue share, you are paid first, and SeatClear runs the technology and support 24/7.

Sanctioned, not scalping

The ceiling on every resale is your own walk-up fare, so no seat ever costs more than you would charge for one more, and a gouging headline is structurally impossible. That cap, the sold-out-only trigger, loyalty gating, and identity drawn from your own records make bulk-buying and touting unprofitable and traceable. Listings can only originate from tickets synced to your records, so a fake listing cannot exist, and every transaction is verified twice, by SeatClear and by you.
