Australia's Qantas Airways resumed limited superjumbo flights Saturday, with the take-off of a fully-loaded Airbus A380 from Singapore.
Qantas chief executive Alan Joyce joined the first leg of the flight to London via Singapore.
Joyce told reporters that he was 100 percent comfortable with the operation of the aircraft.
The airline grounded its six A380s after a superjumbo's engine blew up midair on November 4, forcing an emergency landing in Singapore.
Inspections showed problems with several of Qantas Airways' Rolls Royce Trent 900 engines that required turbines to be replaced or modified.
Qantas is putting just two of its A380s back in service while modifications are made on engines on other aircraft.
