By "global solution" do you mean taking a good trip a senior pilot wants and giving it to a junior pilot so he/she can have a line? I'm pretty sure DALPA doesn't allow that.

If the TLV was raised as part of raising reserve guarantee, then there would be higher ALVs and maybe less reserves needed too, but there would be less lines too. Less pilots needed too.

Less pilots means that some the junior reserve guys asking for higher guarantee would be bumped off their aircraft and displaced to a different aircraft or base. Some people on the junior equipment would be displaced to the street. (barring a political decision to keep manning fat for future growth).

Everything is interconnected.
