Maybe they'll make the 739 2x3 seating!
Then it'll sit the same as the MD88. So it's just a long range MD88?! Just one costs $4M and one costs $80M but maybe $40M on discount or something.
Out of curiosity, as a wave of the future, if we configure our supposed 739s the same as say CAL or Alaska Delta Connection Airlines, then in first class we'll lose 6 seats and 10 seats respectively over say our 75Xs (the 752s with the seats).
The coach seating would be within a few seats of each other.
If you did the A321, which has two JS's I believe, is the same as the 739s.
