See, you don't even know all the details why, but you can't help yourself calling them foolish and deriding them. It was their decision, and I'm sure every aspect was over analyzed before making the jump and it was lucrative enough in the ways that mattered to them to make the switch. A very high probability that the money was equal or better, more time at home with the family, better quality of life when on the road, better destinations than hub and spoke 121 flying... Maybe a bonus structure, who knows. I tell you one thing though, they'll never have to wait for the hotel van again. A rental car will be planeside every trip for the rest of his career. There are a lot of reasons people work various jobs. Different strokes for different folks.
You don't have to tell me. I know a 10th yr AS Capt who left for Spirit.
It is what it is.
MOST Captains I flew with who had worked for multiple airlines, had they stuck with their first big/major carrier they went to, they would have come out far, far ahead than they did in the end. There's a reason we have a saying of waiting until age 65 to see if we made the right move. That is largely true, especially with the cyclical industry and luck, timing of everything. Those things are beyond control. But how many employers one works for, and how many jumps they make, definitely comes into play - and usually for the worse.
There's the example of Zap, but at least in his case, his moves were forced by furloughs. That is entirely separate and understandable. But I believe even he mentioned that he made some bad moves (eg, maybe not accepting a recall when it came).
Now you compare that to voluntary moves made without a threat of furlough. No offense to the one gentlemen here, but there's a JC member who got hired at United at 26, and left after ~5 yrs for Fedex. Or replace that with CFI AP's Corpie company. Either case. No offense to that guy, but I think it's absolutely a bad move to have done that. Especially in the last 15 yrs, which represents about ~60-70% of pilots today at major airlines.
Chasing the greener grass has a potential for back firing.
Side note, extremely minor, I have never cared for hotel transportation (as in look at it a negative way, versus renting a car), but in the post-Covid world I haven't really had to wait for any pre-arranged ride. We seem to have moved away from hotel shuttle only (although that is the only option in a couple cities) to a private company model.
