Well, a lot of people here seem to think United is secretly in cahoots with you all and wants to buy you.
I presume he's a United pilot explaining why that doesn't make sense.
If you really think B6 is in trouble, get out NOW! Don't wait for a hopeful merger. I waited too long at NK and lost tons of seniority where I am now as a result. If you think B6 will be fine (and I hope it will be), stay and enjoy your life. I would have some cash savings just in case the **** does hit the fan.
