Flights usually start boarding between 30 to 50 minutes before the scheduled departure time. This allows enough time for passengers to check in, clear security and customs, and make their way to the boarding gate.

The "wait" to board a plane actually consists of two stages: the time spent at the gate and the actual boarding process. Most airlines recommend arriving at the gate at least 30 to 45 minutes before your scheduled departure. The actual boarding process for a standard narrow-body jet (like a 737) typically takes about 20 to 25 minutes, while a large wide-body aircraft (like a 747 or A350) can take up to 45 minutes to fully load. In 2026, most carriers use "zone" or "group" boarding, starting with pre-boarding for those with disabilities and families, followed by first class and high-status members. If you are in the last boarding group, your "wait" at the gate will be longer, but your time on the jet bridge will be shorter. To minimize your total wait time, it is a high-fidelity strategy to only head to the gate once the app notifies you that boarding has actually begun, though you must be careful not to miss the "final call," which usually occurs 15 minutes before the "doors closed" time.
