IMHO, the US3 have no chance of winning this battle. ALPA and A4A might lobby congress to alter the open skies agreement but they are going up against a formidable opponent. The lobby for ME3 would include the ruler of the UAE talking directly to the POTUS and involve billions in aircraft orders, defense contracting, and issues of national security. For all the Americans at EK that want to come back to the US3, I would stay where you are. This will have a very negative impact on your career. Especially if you are at the bottom of the list.
