It's a shame they did away with the 757 and decided to stretch the 737.
Why don't they just revive and juice-up the 757?
Boeing actually did float around the idea of a "757NG" but obviously the airlines said "no thanks".
Also, the 737-900ER really isn't a replacement for the 757 but more a competitor to the A321.
The 757 is too heavy for most routes, and it has a different cockpit than the 737NG's. If you don't need the range of a 757 to cross the Atlantic, a 737-900ER has enough range to cross North America while being lighter.
Continental is taking its 757-200's off of domestic routes and putting them on transatlantic routes from the east coast especially from Newark. They are replacing their 757-200's on domestic routes with a combination of 737-800's and 757-300's.
