Didn't a thing come out a couple years ago that the old grainy CRT screens weren't being made any more and airlines would have to convert them to LCD at a signifigant investment? I think a lot of airlines started retiring the ratted out first gen AB after that.
Surprised Allegiant isn't snapping them up. When I was there we were pulling parked airplanes out of the jungle and even grabbing former Aeroflot jets that smelled like a dirty ashtray. But those hoopties were paid for with cash!
