How many airports are setup to >handle mid-door boarding (Toronto has movable Jetways - but slow to >get into position, while Chicago has fixed position Jetways)? Believe it or not, the 757 was designed with the idea that boarding through door 1L would be the standard. Door 2L was designed to allow it to be used as an alternate boarding door, if desired. Door position was determined primarily by evacuation requirements, I believe. The right hand doors are designed for galley servicing. We do pay attention to boarding when designing a new airplane. The larger the airplane, the more attention payed to boarding. As long as the aircraft can be boarded in less than twenty minutes, it doesn't matter much. Refueling, cabin cleaning, baggage & cargo handling, all take time, so a total thirty minute turnaround is about standard for single-aisle aircraft. Interestingly, people are quite motivated to get off the airplane, so the passenger/minute rate jumps way up compared to boarding, where everyone tends to lollygag in the aisles. :-) I have no idea how many airports are set up for door 1 vs door 2 nor even left (standard) vs right (creative).
