I don't have a dog in the fight either. But the guy did mention the word "travel bank". UPS/FedEx has them also. He did not imply at all that the company buys the ticket FIRST, then he opts out.
It's my understanding that if the pilot at some of the aforementioned companies use it, it's more along the lines of the pilot telling the company something like;
"DON'T buy me that DH ticket that routes me through (insert legacy hub here). I will find my own way home, thank you. Put the balance (or applicable percentage/accepted fare) into my travel/deviation account."
Not once did said pilot put his JS agreement in jeopardy. He's doing nothing different than a pilot electing NOT to take his dead head back to his domicile when he can just jumpseat straight home from wherever he is on another carrier.
Nope.....at Fedex the travel bank is used for when the crewmember finds a cheaper way (not free on the jumpseat) or goes a different route than the company books him.
