I clicked in your thing.....I can't really understand it....but as long as you can...........it seems you are projecting what equip you can hold and when you could .....I will only say you should know by now that predicting future things like this subject to way to much volatility to eliminate all the speculative risk that's involved with changing legacy teams. One data point you do know is retirements...published on this very website.

as far as narrow body upgrading after probation...well certainly that WAS NOT the results of the last bid which closed March 13. That is not to say it may one day return. Your decision involves risk. It appears you are 37, and have been at AAl for 1.5 years......already being at a legacy...it's risky........not reckless or endangerment.......but are the rewards worth it???

if it meant a life of commuting I d take it, but otherwise I wouldn't do it.
