Other Boeing pages give very little space to the 737-600. Boeing has sold tons of 700s and will keep doing so. They are now the largest member of WN's fleet and they have over a hundred more comming to them (now with winglets, and a WN captain told me that they are thinking strongly about retrofitting the 300s with them). AirTran's order calls for 700s, though some will be converted to 800s most likely. Aeromexico, Luxair, WestJet and many more are picking up plenty of them. Even Easyjet still has 73Gs comming to them and will not be selling them anytime soon. The 600, on the other hand, in not something anyone is interested in. Anyone replacing a 732 these days can get a bigger plane with better economics, instead of one roughly the same size with not much better economics. Looking at the 738/739 specs is a little puzzling. They are listed as having the same one-class passenger capacity and same MTOW. The range given for the 739 is 224 sm less than the 738. Thus what the bigger wing and 8 foot 8 inch longer fuselage gets you in the 739 is supposedly the higher cargo volume. Since the bigger wing and fuselage must weigh more, I wonder if the cargo weight allowed in the two planes can be much different at full fuel load. Of course with less than full fuel aboard, higher volume available for cargo can allow bigger weight of the cargo, but also considerably shorter range. The 739 seems a little bit of a combi. I couldn't find anything about the length of the 737-600 and 737-700. >> The problem with the 739 is that they did not design more Emergency Exits into the airplane, so they can only carry as many PAX as the 738. If you look at the combined F/Y numbers, they hold more than the 738 (this is exactly why AS and KL ordered them). The new "Super 737" that QF and DJ are expected to launch will have more exit doors and is rumored to hold a few more PAX than the A321, putting it in 752 territory. Also, they are planning on giving it 73G type range, making thin transatlantic flights (like the CO 752 flights) possible.
