Your chances of getting on a standby flight vary dramatically depending on the day of the week, the season, and your priority level. For the average "same-day standby" passenger looking to catch an earlier flight, success rates are typically around 60% to 70% on mid-week, non-holiday routes. However, during peak periods like Spring Break or the winter holidays in 2026, flights are often "weight-restricted" or fully booked with "no-shows" being rare, dropping your odds significantly. Priority is everything: "Elite" loyalty members and displaced passengers from canceled flights are at the top of the list, while "buddy pass" travelers or non-revenue employees are at the bottom. To maximize your chances, travel with carry-on luggage only, as gate agents are far less likely to pull you from standby if they have to search for a checked bag in the hold at the last minute.
