Luxair and Boeing today announced that the Luxembourgian airline has chosen the fuel-efficient 737-8 MAX 8 to expand its single-aisle fleet with an agreement to acquire four jets.

Luxair will initially lease two 737-8s that are due for delivery for the summer, ensuring the airline provides its customers with increased capacity and connectivity to more destinations for the busy summer travel season. It has additionally placed a direct order for two 737-8s.

The 737-8, seating 162 to 210 passengers depending on configuration and with a range of 3,500 nautical miles, is the market’s most versatile single-aisle airplane, capable of operating profitably on short- and medium-haul routes.

Luxair operates a fleet of 19 airplanes, including eight Next-Generation 737s.
