ANKARA (AP) – Turkish Airlines has ordered eight Boeing 737-800 passenger planes in addition to its previous deal to buy 15 planes, the company said in a statement yesterday. Turkey’s national carrier, which agreed to buy 15 B-737-800s from Boeing in 2004, placed the new order after securing funding for the payment, said Recep Guvelioglu, a spokesman for Turkish Airlines. The company also plans to buy 36 planes from Airbus, as part of its largest expansion plan. The last time the company expanded was in 1997. Turkey was forced to put new purchases on hold following a deep economic crisis in 2001.
