The merger (which would create the world’s largest airline) needs the approval of the U.S. Justice Department and the Department of Transportation. The companies are aiming to have the merger completed by September.
The sticking point is about whether or not the combined company will agree to sell slots (take off and landing rights) at Reagan National Airport outside Washington, D.C. If the merger is approved, the new company would have control of 68% of the slots at Reagan National, reports Reuters.
In May more than 100 Congressmen asked U.S. regulators to allow the new airline to keep the slots. The airport is used by many congressmen in their flights to and from the capital, reports Reuters.
