Q: At what point does a standby passenger become a passenger with full rights? After being admitted as a standby passenger on a recent Delta flight, I was asked to relinquish my seat when a regularly ticketed passenger arrived just as the door was about to close.
A: According to Neil Monroe, a spokesman for Delta, it is unusual for a standby passenger to be asked to give up a seat once the passenger has boarded the airplane. Delta's policy dictates that a passenger with confirmed reservations must show up at least 10 minutes prior to scheduled departure or risk losing the right to a seat if the plane is full. Mr. Monroe said there are rare circumstances in which a standby passenger who has boarded might be bumped -- for example, if a regularly ticketed passenger has a series of international connections to make and cannot travel at any other time. Such decisions are made by the agent in charge at the gate.
Most other carriers, including TWA and American Airlines, have similar policies. Martin P. Heires, a spokesman for American Airlines, says a standby passenger, once boarded, has the same rights as a regularly ticketed passenger. A TWA spokesman says the airline mayyield in favor of the late passenger with a reserved ticket if the ticketed passenger also has a boarding pass. Rather than automatically asking the standby passenger to leave, the spokesmen for both airlines said the gate agent would probably ask for volunteers.
When a standby passenger on any airline is asked to relinquish a seat, the airlines are not required to offer any compensation. Hoyte Decker, assistant director of consumer affairs for the Department of Transportation, said that to qualify for compensation, a person must have confirmed reservations. Even though a standby passenger, once on board the airplane, may hold a ticket, the status block of the ticket would reflect the passenger's lack of reservations. Mr. Decker said his agency encouraged airlines to ask for volunteers who would be offered some form of compensation in return for delaying their departure.
