Nok Airlines has firmed a previously announced order for 15 new Boeing aircraft, including eight 737-800 NGs and seven 737 MAX 8s. It also intends to convert one of the 737-800s into a 737 MAX at a later date. "The 737 is the backbone of our fleet and has fuelled our growth over the past 10 years," said Patee Sarasin, CEO of Nok Air. "This order is a key part of our disciplined fleet strategy." The order was first announced as a commitment at the Singapore Air Show in February and is valued at $1.45bn at list prices. While Nok Air currently operates a fleet of 15 737 NGs, it is the airline's first direct order with the manufacturer. The deal will also make Nok Air the first airline in Thailand to operate the 737 MAX. Boeing has surpassed 2,000 orders for the 737 MAX programme with the addition of 30 orders from unidentified customers this week. The 737 MAX now has a total of 2,010 orders from 39 customers worldwide, valued at $209bn at list prices.
