I don't think anyone from CHQ has ever said XJT sucks. At least I haven't read it. I also haven't read about anyone from XJT flippin' us the bird...you might be thinking of a Comair thread from awhile ago. The XJT crews I ran into in IAH were pretty awesome. I'm just defending my company like the XJTers. When they do it, it's called pride or something like that.
And about the ACARS...like no one has ever been able to get around THAT thing. And the 170's have them and those numbers are the same as CHQ's...
