Travel Service has announced a firm order for three 737 MAX 8s worth $301.5 million at list prices. The Czech Republic-based carrier originally announced a commitment to purchase the 737 MAX at the 2013 Paris Airshow in June. Today's announcement brings the total number of orders for the 737 MAX to 1,498 airplanes.

The 737 MAX will be 14 percent more fuel-efficient than today's most efficient single-aisle airplanes and 8 percent more fuel-efficient per seat than tomorrow's competition. The configuration includes new LEAP-1B engines from CFM International that are optimized for the 737 MAX, a redesigned tail cone and the Boeing designed Advanced Technology Winglet to reduce fuel use. Other changes incorporated include upgrades to the flight deck displays, an electronic bleed air system and fly-by-wire spoiler flight controls.
