Boeing said on Tuesday that the largest private airline company in the Czech Republic, Travel Service, has ordered two next-generation 737-900ERs for $150 million.

Travel Service will become the fourth European airline to operate the 737-900ER model that was released last year. Boeing said that delivery of the airplanes due to begin in the fourth quarter of 2009.

The Boeing 737-900ER will integrate seamlessly into our highly reliable and economical 737 fleet, said Roman Vik, Chairman of Travel Service. With its added capacity, the 737-900ER will complement our current operation and help it grow more profitably.

Prague-based Travel Service already operates an all-Boeing fleet of 10 737s, including seven Next-Generation 737-800s. The Boeing 737-900ER is the largest member of the 737 airplane family.
