Unlike American, Delta Air Lines shows the Preferred seats it has held back for elite customers, but doesn't allow regular customers to book them until 24 hours before departure.

Airlines routinely block coach seats for a variety of reasons, reducing the pool of available seats to reserve free of charge in advance when you book a trip.

基于诸多因素，航空公司常会锁定一些经济舱座席，这使得人们在预定机票时可以提前免费预留的座位有所减少。
