Did it ever occur to you that the crew of the TUS flight was working a turn and that holding the flight for you would have extended their on duty hours for working that sequence close to or over the federal limit? That, in turn, could very well have caused them to be illegal to work the return flight to JFK. Had that been the case, a lot more pax than just you and you wife would have inconvenienced. It also would have been much more costly to the the airline than the paltry revenue it earned on selling your tickets. I find it curious that you never disclosed how little you paid for that round trip.
