I remember when UA accquiered Pan Am's Pacific division they recevied about 10 L-1011-500's, which they kept in service for about two years. but undoubtably should the UA/US deal go through it would be likely that they would be sold back to Airbus in exchange for more A32X's. As for the Hawaii market, United has been flying there since the late 40's and has the most service from the mainland to Hawaii... obviously for them it is making enough money to fly from 3 gateways to 4 Hawaiian cities. Plus I don't think you can fill up a 747 or a DC-10 with nothing but people who have 40 or 50,000 FF miles to kill.
