The current boarding processes, whether rear-to-front, wilma, pyramid, or other, all fail to provide fast and smooth boarding and tend to create havoc, scrambling, and passengers frustrations.
Using these methods carriers achieve only six to eight passengers per minute, maybe reaching nine or ten with dual aisles, on good days, upsetting airport gate and bridge costs as well as turnaround time.
Passengers dislike the waiting, the rush, the traffic jams and the delays. Calling the passengers is complex, specifying who can board and when, by Class and special cases such as pre-boarding, priority, platinum, gold, silver, sapphire, economy plus or premium, and finally the rest, by rows! The result is often chaos, passengers rushing the line-ups, and ignoring social correctness and rules.
As the economy finally can be re-started, not all corporations will have survived the hiatus. Only the ones who have been able to mitigate the impact of this crisis by cutting costs to reduce their losses will survive. Improving boarding efficiency and providing a secure process to their passengers will give them an edge on the competition, and possibly allow them to gain market share.
