Thai Airways International (THAI.TH) has firmed up a previously announced commitment to buy seven Airbus A330-300 wide-bodied commercial jets, the subsidiary of European Aeronautic Defence & Space Co NV (EAD.FR said Wednesday.

Airbus had announced Thai's intention to buy the planes during last month's Farnborough Air Show.

Deliveries will start at the end of 2011. No indication of Thai's engine choice was given.

On the basis of Airbus' price list, the order is potentially worth $1.49 billion.
