Two items,
1) CAL still owns about 8% of XJT directly, CAL's retirement fund owns about 10%. Many of the mutual funds & institutional investors who have a signifigant position in XJT also have a signifigant position in CAL.
Therefore it is illogical that CAL cut XJT loose without some assurance that Ream, et al would find something usefull to do with those airplanes.
2) Just because XJT does have something worthwhile to do with those airplanes doesn't mean XJT pilots will have anything to do with it. I haven't heard anything recently about XJT Eurpoe, but if and when, you can bet that nobody on your seniority list will be doing any CDG-LHR flying.
So, nobody panic, XJT isn't going anywhere. But nobody celebrate, either XJT hasn't gauranteed anything either.
