Well, their number of 757s keeps getting bigger as they take more deliveries. There was a new one at Boeing Field the other day before all of the thunderstorms.
As for the 767s, they are getting rid of the 767-200s as I think they are not ERs (I could be wrong) and getting new 767-300ERs.
Sorry I couldn't be very speccific as they are getting more and I don't know how many total they ordered but I am sure someone out here knows. I wish they would post something about fleet size on their web site.
What's so bad about 757s? I enjoy them on the SEA-STL route. They have movies on them and are usually good movies. The 757 is great for them as it is so cheap to operate and helps to keep costs down (something TWA needs). They are getting more 767-300ERs for Trans-Atlantic flights but they don't need as many as UA or DL. They need more flights, not more pax. so why do they need a 777 or a 747? All that extra capacity would kill TWA, that is part of what got them where they are, operating half empty 747s accross the Atlantic. And would you PLEASE tell me why the MD80 is a "death tube"?!?!?!?!?!? I have never heard of a glut of TWA crashes involving MD80s, in fact, MD80s are pretty darn safe aircraft. I admit TWA has problems, and they are working on fixing them (a little slowly IMHO) but if they had 747s and 777s like you want they WOULD DIE!
