hey whlinder, haven't seen ya around since bowl season!
you might not like the slogan, but I can't imagine that "ride with the huskies" would work either! LOL
actually, I really don't think the unions would be a problem. Southwest is very heavily unionized, but their labor agreements do not fit the mold of typical labor agreements. they pay among the highest in the industry, but they have the contracts structured to get among the highest productivity as well. unions and management can work together, when both sides WANT to work together.
maybe the 737's could be made more fuel efficient with the winglets, but until you find a way to widen the cabin, the A319/320 is still much more comfortable in coach. compare a UA 737 seat with a UA A320 seat, and you'll see what i mean!
