1. New terminal in BWI is, for all practical purposes, complete. That is, the gates are being used, and the terminal is fully open to the public, with the exception of the new check-in counters. The new terminal is, in my humble opinion, one of the best-looking terminals I've seen, and the food court is a HUGE improvement over the previous concessions. What remains to be completed is the underground fuel reservoirs on the B concourse.
2. DAL and HOU will eventually lose some their ridiculous loftiness in seniority, but I can't say how much they will even out with the other bases. They would each have to lose many captains before they become as junior as even PHX and MCO...I've flown with captains who are in the top 10-20% of BWI seniority who can barely even hold HOU, much less DAL. Plus, if the Wrong Amendment does not get the kaibosh (spelling?), DAL has no room for growth, which is not the case with the more junior bases. I doubt HOU has much more room for growth, either. Any added service will almost surely be on USAir's turf.
