Standby
A status where a traveler waits at the airport for a seat on a flight for which they do not hold a confirmed reservation.
Standby is the condition of a traveler who is at the airport hoping to take a flight on which they have no confirmed booking — either because they have missed their original flight and are waiting for space on a later service, because they are trying to move to an earlier departure after check-in closes for their confirmed flight, or because they are a non-revenue traveler (such as an airline employee) traveling on a space-available basis. Airlines manage standby lists in a defined priority order.
Why it matters
Same-day standby is most relevant to corporate travellers when a same-day flight change is desired but not confirmed. Understanding how standby priority works — what determines whether a traveler clears the list and secures a seat — helps travellers make informed decisions about whether to release their confirmed seat on a later flight to wait for space on an earlier one. Releasing a confirmed seat to take a standby position on an earlier flight carries the risk of ending up on neither flight.
How it works in practice
Airlines assign standby priority based on loyalty tier, fare class of the original ticket, and check-in order. Elite frequent flyers typically clear standby lists ahead of lower-tier members; passengers with premium cabin tickets may have separate standby handling. Standby lists are managed at the gate and are cleared as confirmed seats become available — typically from no-shows and voluntary denied boarding. The traveler receives a boarding pass only when cleared, which may not occur until boarding is nearly complete.
The takeaway
Before releasing a confirmed seat to attempt standby on an earlier flight, assess the probability of clearing the list realistically. On full flights with long standby queues and low no-show rates, the risk of ending up stranded is real. Confirmed seats have tangible value; standby positions are probabilistic. For corporate travellers with fixed meeting commitments, maintaining the confirmed booking and managing the schedule around it is usually the safer operational choice.
