Qatar Airways on Saturday inducted its 15th Boeing 777, bringing the size of its fleet to 80 aircraft, the carrier said.     
The Boeing 777-200LR aircraft will serve long-haul routes from the airline's hub in Doha, Qatar's capital, Qatar Airways said in an emailed statement.    "Just five years ago, Qatar Airways operated 40 aircraft. Today our fleet has doubled in size to 80 aircraft. As our fleet increases, we are able to raise capacity on existing services and introduce new routes," Qatar Airways Chief Executive Officer Akbar Al Baker said.     
Qatar Airways' fleet is set to grow to 120 aircraft by 2013, with destinations also expected to rise to 120 over the same period from 86 destinations now, according to the statement.     
The aircraft delivery is part of a larger, $40 billion order for more than 220 aircraft placed in recent years, the airline said.     
Qatar Airways said it will introduce scheduled flights beginning March 30 to Copenhagen; from April 5 to Ankara; from April 26 to Tokyo; and from June 7 to Barcelona.
