No, there is nothing definite going on for the 69 XJet ERJ's. We know of 4 types opportunities that the company is looking into, and Europe is not one of them. Nothing is set in stone, which is worrisome with less than 6 months before the first plane leaves property.
Personally I am not too optimistic. CAL says they want 44 RJ's for CHQ, coincidentally that's exactly the number of XR's they are withdrawing from XJET's CPA. If XJT cannot find work for those planes, leasing them to CHQ may be the best option, although that wouldn't work out so well for the 400-500 XJET pilots that would probably be cut if that took place. (XJET has never even hinted that they would consider leasing the planes to CHQ, but I remain cautiously suspicious).
If there's a single argument for leaving the regionals, this is probably it. The financial side is just a "shell game" with nothing being cut and dry; you're just a vendor. I have seen nothing that indicates that CHQ is truly cheaper than XJET; I believe CAL is simply doing this for competitions sake, much the same as NWA has done in the past with Mesaba and Pinnacle.
To make this an even more bitter pill to swallow, CAL announced a $200,000,000 profit today. I'd like to think Expressjet helped contribute to that in a meaningful way, considering we currently upwards of 30% of CAL's total system capacity. Apparantly, I'm mistaken in that line of thinking.
