Actually, I wouldn't put it above Alaska Airlines and Southwest Airlines to both place substantial orders for the 737-900ER. That means Alaska Airlines can fly more passengers on longer USA transcon routes and Southwest can use them on nonstops between USA West Coast cites (Seattle, Oakland, San Jose, Sacramento, Los Angeles, Las Vegas and Phoenix) US East Coast cities (Providence, Islip, Philadelphia, Baltimore, Jacksonville, Orlando, West Palm Beach and Fort Lauderdale).
I wonder if Continental will pickup some 757-200's from some of the European charter airlines that switch to the 737-900ER?
