The "if available" is the kicker. I've done the coach to anc as well on a last second ticket. The problem of Swiss cheese language in remains in this cba.
For some reason we don't get compensated for the flexibility our work rules gives the company to move freight. Yes there's some penalties for revisions, but not enough in my mind to start building the church for Easter. They rely on the wishy washy rules we've given them, with things such as the hsby astby schedule flood, reserve line conversion (yes I know this was eliminated but tbd is whenever) back filling line holders into asby, dh in coach or in the back of a 777 to dxb under the " all the that was available" canard. There is no incentive to man correctly because it doesn't cost them anything to use these practices.
We had a chance to fix this, we failed.
