What other info are you looking for? The following is mostly from memory, but Mesa served as UA Exp. for several years, up until UA kicked them out, replacing them with SkyWest (west coast only). At the same time, HP was seriously considering terminating their contract as well. Since that time (2yrs?) they've made a remarkable turnaround, rationalized their fleet and even held onto service (intra NM) that they said they'd have to cut. They also breifly ran RJ service from ABQ to FTW (Meecham Field) and on to AUS (I think, anybody who remembers feel free to correct me), but that died due to lack of demand. Recently, during the Commair strike, they'd announced service into CVG, but promptly cancelled it when Commair returned to the skies.
Sorry this is so general, like I said, its mostly from memory of news clips and such.
