What Really Are The Major Advantages Of The B739?

Tue May 08, 2001 11:41 am

Other than the longer fuselage, of course. But, both the 738 and 739 are only allowed to carry 189 pax in maximum high density seating, due to the exit row layout configuration.I guess my question is, doesn't the 737-800 even have a slightly better range advantage, over the -900? So why did Boeing even build this variant?Perhaps it was to meet specific airline customer specifications? Or, was this basically, Boeing's answer to the Airbus 321? Why did Alaska choose, or wait for the -900 over the -800, which could have delivered to them alot sooner?Just my curiosity getting the best of me.

Both have a max seating capacity of 189 because of FAA regulations having to do with the number of exits on the plane and how many people can safely exit the plane in an emergency through the available doors. The 900s can technically hold more people, but more exit doors would have had to been designed into the plane.
But still 189 seats would be in a single class configuration. There are really no airlines that are gonna have it that way. So in a 2 class configuration the 900s will be able to hold more people. I will have to look up what CO's 900s seating capacity will be as compared to the 800s which hold 14F/141Y. Any of Gordie's kids out there know offhand?
About performance, that I don't know but since the 900 is longer it means it has longer bins which means more space for cargo.

An educated guess only:
1) The longer fuselage does allow for more first class seating without sacrificing coach capacity, a plus for the AS Mileage Plan base. (AS has a very generous upgrade program)
2) About 300 cu ft more cargo space than the 800, valuable for the sometimes staggering amount of Alaska Fish shipped as cargo.
3) The prestige of being a launch customer as opposed to another buyer.

The advantage of the 739 is more seating capacity in a typical first/economy layout, as the fuselage is longer; that also, of course, means more cargo capacity. Since the 739 is larger and heavier than the 738, is will give up some range and a range of "only" about 2500 miles is inidcated for the 739. The shorter range really should not make such a difference to most airlines, as most 737NG aircraft are not assigned to long range routes anyway. Look for AS to use the 739 on high capaicty routes out of SEA, CO on the heavily travelled EWR-Florida routes and KLM on routes out of AMS to major European cities (KLM might go all 739 to LHR replacing its mix of 763 and 737 aircraft on that route, we shall see.)

Your point is interesting because many European charter airlines, who have purchased the 738 in large numbers, have not yet shown much interest in the 739; why? Your point, they already cram as many seats as possible into the 738 as allowed by the laws so the 739 brings no additional benefit to them.

I believe that the genisis for the -900 was purely from Alaska and Continental wanting a slight stretch for more first class capacity. I may be wrong, but for some reason, that sticks out in my head.
