Looks like the US Airlines want to discontinue or modify the Big 3 Persian Gulf carriers subsidies via air treaties. It will be interesting as all 3 push deeper into US markets. Not sure which if any US carriers directly service Dubai but probably none service Abu Dhabi or Doha. Definitely a storm brewing and Canada has also sought restrictions of the Big 3 Gulf Carriers.
The US service is obviously substandard in comparison to all 3.
