All you people who think this idea is socialism...guess what? If you're a part of ALPA, and if you sit on a seniority list, you're part of a socialist system. You're all socialists. Labor unions are socialistic at the core. If you don't want to be a socialist, then you should negotiate your own salary, and upgrade should be based on merit. The concept of a onelist for all airline pilots is nothing different than how non-RLA unions in other industries work. If you were a dockworker, you'd join the union down at the union hall first before you could go out and get a job. Everybody worked under the same rules and pay. The different employers all had to pay their dockworkers the same amount of money, they couldn't compete with each other by cutting their worker's pay. They had to find their profits elsewhere. This is how the longshoremen have gained so much, by having all of the workers standing together, instead of undercutting each other's wages to get work.
The opposite is true in the airline industry. The employers have a unified strategy that keeps the pilots divided and fighting each other for work, continually driving wages downward. It has been amazingly successful. As of now, ALPA is nothing more than a professional organization that does some capital hill lobbying, some support for contract negotiations, and maybe fight to get a fired pilot his job back. Other than that, it has no function. It is no union.
Yes, some people would have to give up some, while some people would gain some, but in the long run, and it may even take a generation or two, but everybody will have more if pilots actually could unite and be one block against all management. Airlines would then have to actually find efficiencies in their operations and increase revenues to increase profits instead of merely gutting pay.
Unless full cabotage is allowed in the US, a union hall could work in the airline industry. As long as there is geographic protection, union halls have been successful. For the dockworkers, employers couldn't unload goods bound for the US in Singapore, where people are cheaper. They had to unload goods bound for the US in the US. So there is no getting around having to use the union labor. While it failed in merchant sailors because employers could merely go use a ship registered in Liberia crewed by Filipinos who work for rice balls to avoid using US ships.
Pilots are notoriously hypocritical when it comes to these issues. They are union laborers yet think of themselves as high paid white collar professionals. They complain about the state of industry yet vote for anti-labor groups. What can I say? Unless there is a change, we will always lose.
