Wow, clearly you’re mad the young mustache guy is at mainline and you’re not.
Stay mad.

The guy was trying to do you a solid. If the back was full, and there were other standbys ahead of you, you weren't getting on.

He did the math, saw that he was a lock for a seat in the cabin, and turned down the JS so you can have it. Like a good ALPA member does for a fellow pilot.

You don't have to thank the guy if you don't want, but at least don't disparage someone for trying to hook you up.

Oh I would…if it comes down to a pass rider getting a seat or the other jumpseat getting on, I’m taking the seat in the cabin and helping that pilot get to their destination. Take care of your fellow pilots first and make sure that you get to where you need to and they get to where they need to regardless of what ID they wear. If there aren’t any pilots listed and I can get a pass rider on by taking the jumpseat I will, but if me taking a seat in the back means getting a lower priority code pilot on the jumpseat then I’m taking the seat in the back.

Yeah, not me. Those are company benefits for employees and their families. I wouldn’t expect a DL, AA etc. guy to screw over their fellow employees either to get me on, but that’s me.

Maybe I’m misunderstanding this entirely. The way I’m used to you have a listing for any seat on the plane, all by seniority order. As a last resort, if the cabin is full, the jumpseat(s) get assigned, again in order of seniority (to people eligible for it). I’ve never heard of people being allowed to double list out of order etc. (and the carriers I’ve worked at are ALPA too) where I am from that’s frowned upon because you block several seats without ever actually using them.
If that’s possible at UA I can get his patronizing stance. He knew he was gonna get a seat in the back and was now offering his Jumpseat to me (even though it’s not even him deciding who gets it ultimately). Yes people can argue that he was doing me a solid, however imho it’s not the way it’s supposed to be. If you get a seat in the cabin you should take it and not mess up the system by listing for the JS only to give it to someone else at the last minute to stand there as a star.

“I know there are plenty of seats on this plane and I’m double listed, top of the list and will get a seat for sure, so let me offer this beggar from another airline a seat and stand here as a hero”
the only thing missing was him videoing himself 😂

There is no “supposed to be.” Every airline is different. At United, we can and are encouraged to list for both the cabin and the JS, allowing the most junior/lowest priority pilot to occupy the jumpseat if available. Some recent changes to our IT may make this practice less important, though, but that won’t affect you.

Oh I see. So should I be doing the same when I list in the future? Or is this automatic? Do I need to tell them at the podium that I want to be listed for both? I always assumed a listing for the JS meant an automatic flowback if there is space in the back.

Three pages of this crap and you still don't get it. You don't have to ride on United if you don't like their policy.

Based on your post history, you don’t work for a US 121 carrier, so unless you want to pay for a zed fare to list in the back, you wouldn’t list twice. Listing twice is a United pilot thing. Offline jumpseaters just list at the gate as you did and are flowed back if seats open after all higher priority non-revs are cleared.

I think the other pilot was simply telling you he got a seat in the back from his cabin listing and the system worked as it should. Like most carriers, we can see everyone on and offline listed for the pilot and FA jump seats as well as everyone in the cabin.
