OneWorld member American Airlines transports roughly 86.13 million passengers a year on international and domestic flights, ranking it third in the world. It is ranked fourth amongst domestic carriers, transporting over 65.77 million passengers domestically each year. If the number of passengers stayed the same, the union would transport over 41.37 million passengers internationally each year, which would bring DAL from eighth in the world, to third, coming in just behind Lufthansa's 44.46 million passengers a year and Ryanair's ( RYAAY) 71.23 million passengers. This brings up some concern that a Delta-American combo would draw scrutiny from anti-trust officials. However, the Wall Street Journal writes, "Delta has conducted an antitrust analysis and believes with concessions, it would have a good chance of obtaining regulatory approval."
