yeah, 737 is cheap and not too fast. that's why. the plane is not important but the equipments inside is the heart part. who cares what plane it carries on. but, i do wonder, when the 777 comes out, why not use the new jet? it can save fuel which means can stay in the air longer. well, of course, they might use it after the market are full and the contract start to slow down......it is a good way to put those old jets in use anyway.
