Other airlines have tried variations on the system before, even as most eventually revert back to the current system whereby higher-paying first-class and business-class passengers board first, followed by passengers from the rear of the plane to the front.

In 2026, the boarding sequence on most major airlines follows a strictly tiered priority list designed to maximize efficiency and reward high-value customers. The very first people to board are "Pre-Boarders," which includes passengers with disabilities who require extra time, unaccompanied minors, and active-duty military members. Following them is "Group 1," which typically consists of First Class or Business Class passengers and top-tier elite status holders (like United Global Services or Delta 360). Next are the mid-tier elite members and those who have purchased "Priority Boarding" as an add-on. Some airlines, like United, have shifted to the "WILMA" (Window-Middle-Aisle) method for the remaining economy passengers to speed up the process by filling the window seats first. This reduces the "aisle blockage" that occurs when passengers have to stand up to let others into their row. For 2026 travelers, the "pro" move is to carry a credit card affiliated with the airline, as this usually grants "Group 2" or "Group 3" boarding, ensuring you find overhead bin space before the plane reaches capacity.
