An airline focused its attention on the passenger boarding process to determine whether there was a better way to board. The existing process consists of three groups A, B, C, with no assigned seating. Depending on passenger check-in and arrival time, passengers are given a sport in a group. Those first to check-in received choice places in the A group. The last to check-in ended up I the C group and had a choice of only middle seats in the back of the plane upon boarding. Seven different alternate boarding scenarios were designed and tested. They included

• New family pre-boarding behind the "A" group of first to board passengers.
• Family pre-boarding before anyone else but seating choices limited on-board to behind the wing.
• Six boarding groups (within A B C groups) instead of the original three A B C groups.
• Assigned boarding gate line positions based on both boarding group and gate arrival time.
• Single boarding chute at the gate but up to nine groups all in one queue.
• Boarding with a count down clock to give customers an incentive to get in line and board quickly , incentives given out if everyone was on time.
• Educational boarding video to make the boarding process fun, inform passengers how to board efficiently and provide another way to promote its brand.
