Standby seating is rarely a simple "first come, first serve" system; instead, it is governed by a complex priority hierarchy used by the airline's automated systems. In 2026, the primary factor determining your place on the list is your elite status within the airline's loyalty program. After status, the "fare class" of your original ticket—whether you paid for a full-fare flexible ticket or a discounted economy seat—plays a major role. Other high-priority passengers include those who were displaced by an airline-initiated delay or cancellation (known as "involuntary" standby). Only after these priority groups are satisfied does the "check-in time" act as a tie-breaker. For airline employees or their family members traveling on "buddy passes," the priority is much lower, and they are usually the last to be cleared. If you are aiming for a standby seat, checking in as early as possible is still a "pro tip," but it will not help you leapfrog a Diamond or Platinum member who joins the list after you.
