Bangkok - Thai Airways evaluates alternatives for its fleet renewal program. The Airbus A350 and Boeing 777X are most likely to replace the aging widebodies in the fleet.

Thai Airways plans to order 23 new widebody aircraft to renew its fleet. The ultimate goal of the Asian carrier is to standardize its fleet while expanding its existing network.

The airline's fleet includes a mixture of widebody devices made up of 15 A330-300, 12 A350-900s, six A380s, eight 747-400, 32 777 family aircraft and the eight 787 family aircraft except the 787-10.

Both the Airbus A350 and Boeing 777X seem to be good alternatives for a fleet standardization when the current fleet structure is taken into account.

So far Thai Airways has always split its orders between the European manufacturer and American manufacturer. Now the aviation community wonders if the carrier will go for a split again or not.

Thailand's national airline is expected to reach a decision soon after negotiations with the Thai government about the future order.
