Thai Airways International has signed Block Space Agreement to utilize two Boeing 777-200 Long Range Freighters operated by Southern Air Inc. The agreement makes Thai the first operator in the region to offer this capability to its cargo customers, from the most advanced B777-200LR Freighter in term of fuel efficiency and low carbon footprint freighter aircraft ever built with more than 100 tonnes carrying capacity, the carrier said. The two aircraft will arrive in early 2010 and will possibly be put on a Bangkok to Europe route initially and later expanded to others such as Australia and USA.
