In the ongoing fight between American and Gulf airlines, Gulf carriers take their battle over accusations of unfair subsidies and competition to the US.
The American airlines say that Emirates, Qatar Airways and Etihad would be nowhere without the $42bn in subsidies they have allegedly received from their governments.
The Gulf carriers deny they have been subsidised, but US lawmakers are now pushing for the government to freeze agreements that allow Gulf air carriers access to US skies.
Research filed with the US Congress also shows that US airlines have received $155bn in subsidies dating back to 1918.
Counting the Cost talks to Qatar Airways CEO Akbar al-Baker, whose airline alone has been accused of receiving $16bn in state subsidies.
