Gee Wally, I think we all owe Bambam a big apology here. I have to wonder if his decision will be any easier now that he knows what corvettes are made of (or do we... did we ever get that settled?) It does serve for fantasitc entertainment, though. Almost beats renting a movie.
Anyway, when I was doing IOE for my second airline back in '97 (Lone Star Airlines, of course!) my IOE captain was trying to get on at SWA. He finally did that year, and heck, I've lost touch with him but I bet he's a captain now, unless he wants it in DAL in which case he's got another 16 years to upgrade. I asked him if he had applied to any other majors, and he said "NO, I never applied to any other major because I don't want to work for any other major." That seemed like simple career advice to me, in spite of what the snake oil salesman in Atlanta might say. I never wanted to work for another company, so I didn't apply to any other company. I also wanted to be able to show up up to my SWA interview and be able to tell them just that with a clear conscience (I had to look that one up in my children's dictionary to get the spelling right). I also knew that JB was a fantasic company, absolutely, and no one could ever say anything negative about them (actually, I did fly with an FO a year and a half ago who said that her friend's cousin's uncle had been hired at JB. She said that he said that he said that JB's training was VERY hard and that people were washing out left and right).
Anyway, I also knew that if it ever came to it, it would be a really hard decision to do what Bambam has to do. So I figured if I didn't make it into the pool at SWA, THEN and only then I would shoot my stuff out to JB, then Fedex, UPS, Alaska, ATA, etc., all of which would be fine companies to work for. Then I could reapply at SWA two years later, but thankfully it didn't come down to that.
Now Bambam, I know that none of that helps you at this point.
I guess for you I'd thank my lucky stars (somewhat of a misnomer) to be as fortunate as you are, and then go with some of the previously posted advice here that I echo. JB is a great company and I think that their long term chances for survival are just about guranteed. Heck, SWA's chances for survival in 1973 were NIL and look how they turned out! I think pay and benefits will be a wash long term, so it really boils down to commuting. If you don't like the SWA domiciles, then you'd commute either way.
But if you live in a SWA domicile you'd be NUTS not to come to SWA. If you live in JFK I'd stay at JB. It's all about giving 100% of who you are to God, country, family, and your employer, so I'd go with whatever airline will help you do just that.
Good luck, my friend.
