Here are five ways a tie-up would transform the airline industry:
Higher fares
Passengers in Europe and Asia can expect ticket prices to rise, according to Bloomberg Intelligence analysts, as the merger partners take capacity out of the market. That would lower pressure on competitors that fly similar routes.
Mega-hub
“Etihad and Emirates could split focus by airport to different regions”
Planemakers get squeezed
Much of the potential for efficiencies in a merger would come from reducing overlap on routes, which would lessen the need for more aircraft.
Antitrust woes
Emirates is already the dominant carrier for many destinations in the Middle East, India and Australia. That means the carriers would likely be forced to drop routes or slots at major hubs.
Politics
An agreement that provides for greater transparency in financial reporting by the government-owned carriers was reached this year, but a combination of the two Gulf carriers could be seen as a bailout for struggling Etihad.
