go-show
The situation where a passenger checks in at an airport in the hope of getting an earlier flight than was reserved.
go-show: passenger gambling on an earlier standby seat
A go-show is a passenger who arrives at the airport with the intention of being bumped up to an earlier flight than the one they have booked, usually by volunteering to take a standby seat if one becomes available. Unlike a no-show (who fails to arrive) or a regular passenger, a go-show is present and checking in early in the explicit hope of catching a previous departure. The term sits at the operational intersection of airline revenue management, gate operations, and passenger scheduling.
The practice is most common on routes with frequent service, where multiple flights to the same destination depart within hours of each other. A passenger with a 2 p.m. reservation might arrive at the gate by 10 a.m., check in, and position themselves for assignment to an 11 a.m. or noon flight if load factors permit. Airlines manage this through standby lists and priority rules. Some carriers discourage or actively suppress go-show behavior because it complicates seat inventory control; others tolerate it when load factors are low enough that empty seats would otherwise go unfilled.
Revenue impact and operational friction
Go-shows create operational friction because they sit outside airline revenue forecasts and yield management systems. A go-show who secures an earlier seat is revenue-neutral or negative to the airline if that earlier flight would have had empty seats anyway, but represents displaced revenue if it means bumping a paying passenger from standby or denying a higher-fare customer. Ground staff must manually flag go-shows in booking systems to prevent double-counting or overbooking situations. Gate agents at busy airports are generally instructed to discourage go-shows or to refuse early check-in, particularly on flights where load factors are already high.
The behavior is distinct from oversale management (where airlines deliberately sell more seats than available) and from intentional rebooking for schedule changes. A go-show is entirely passenger-initiated, assumes voluntary airline cooperation, and carries the risk of missing the original flight if the earlier one fills. Many carriers now make early check-in impossible without explicit agent interaction, partly to reduce go-show activity and the manual overhead it generates.
