What about Alaska signing a code share with these guys? JetBlue and Virgin America also have a code share with Emirates. Crickets from ALPA on airlines that employ pilots they represent signing deals with the ME carriers.
Maybe the best protection from these guys is to sign a JV and guarantee that 50% of the global flying belongs to U.S. airlines? If AF/KLM/Delta went into a JV with Emirates and negotiated that half the Europe flying was AF/KLM and half the U.S. flying was Delta, maybe we have a chance of saving half the flying? Just an outside the box way of dealing with something that probably won't get put back in the bottle at this point.
