I read some place that the 739 although being longer than the 738 has to have the same number of passengers as the 738. This I understand to be due to the number of emergency exits and evacuation times. If this is the case, how is the 762 able to get away with this same number of exits (6) in roughly the same locations and yet carry quite a few more passengers. Also, was it ever looked into to have a third set of doors right before the wings ala 757?
Thanks for your replies.
