Fares notwithstanding, Champion Air is kind of exempt from this argument. They are basically charter only, as I understand, and they only fly 727's, which are not exactly fuel-efficient. I see them at Hobby all the time flying sports charters in and out... I'll miss seeing those three-holers there, belching black smoke out behind them on the take-off roll and climb-out.
So, now we're up to 6 on the year:
Aloha
ATA
Big Sky
Champion Air
SkyBus
SkyWay
Any speculations on who's next? My guess would be another Regional or LCC - let's examine, shall we?
Virgin America - offering low fares and good services, I'm not sure how they're doing profit-wise, but they have Branson's deep pockets to keep them afloat.
JetBlue - They had their woes the first year or so, but by utilizing the ERJ-190 on some of their less popular routes, they've managed to move past that and do pretty well. I don't think they're going to go away any time soon.
Southwest - Yeah right, not even worth mentioning. Definitely not going anywhere.
Airtran - there's an interesting prospect, I don't know much about them or how they're doing. They do have a two aircraft type operation, which is pretty good for the bottom line. I wonder how a merger between them and Midwest Express (the only other domestic airline to use the 717) would play out? Has this been tried once already?
Midwest Express - In addition to their pax service, they also do a lot of sports charters. Aren't their airplanes an all business-class configuration? I think I remember reading that somewhere. My impression is that they're on decent footing, despite shutting down Skyway and farming those routes out to SkyWest.
SkyWest - This regional giant and its subsidiaries (Comair) are not going anywhere.
Mesa - Ditto SkyWest.
ExpressJet - As much as I hate to say it since they're based here in Houston, this seems like it might be a likely merger or closing candidate. Their bread-and-butter is their contract with Continental to do the Continental Express service, but they have lost several of those routes now to Colgan flying Saab A340's out of IAH, B1900's and Dash-8-200's (and now Q400's) out of CLE, and Dash-8-200's and Q400's out of EWR. Additionally, they have lost even more routes to Chautauqua flying E145's and CRJ-200's in CoEx colors too. I had heard at one point that they were going to do some Delta Connection routes, but I'm not sure if that ever came to be or if they did, if that's continuing. They did fly some routes for JBU while the software was being fixed on the E195's, but I think that's long since ended. Also, they have their own stand-alone service now, but that's limited on which markets they can serve due to their standing non-compete contract with COA.
Colgan - This airline is really expanding their routes as the airlines realize that jets on short-haul routes are not profitable. This will be even more so with the ever-increasing numbers of Q400's in the fleet. They are now owned by Pinnacle, so there is a possibility that the Colgan name will go away some day, but the airline itself won't be going out of business.
There are many more, but I don't have time to go into all of them right now. From what's been listed here, my money would be on XJet either folding or getting gobbled up by someone else. I'd love to hear the thoughts of those more knowledgeable than I...
