To be clear, unlike what slowplay stated, the LCA trip pull thing is NOT industry standard.

Only united has the 75% thing-- US has some but it's overall a different deal, and the AA thing has been explained to me several times but I can't quite make heads or tails of it. Virtually all other airlines (FDX and the regionals, too) are similar to what we have (with varying recovery obligations).

It is a MAJOR concession that will affect all FOs as well as junior CAs.
