About Aero mark

On June 15, 1984 Aero Mark fueled its first customer, a Western Airlines 737. Now in 2016, Aero Mark is in its 31st year of service. We call our primary facility AMXL; XL for extra large, as it is the largest and finest FBO building in Idaho, and can hangar aircraft up to the size of an MD-80. You don't have to fly an aircraft that big to get our great service. Aero Mark still lacks fees like ramp and facility and keeps its prices very competitive. All the best owner, pilot and passenger amenities are available and Aero Mark's thoroughly trained and experienced line crew will handle service safely and efficiently. Through our affiliates, maintenance, avionics, fixed wing flight training, rentals and charters, and rotorcraft training are all available.

Welcome to Aero Mark!

About The Red Baron

Aero Mark’s sister FBO, The Red Baron, has a long and distinguished history. Built in the mid 1930s by President Roosevelt’s Works Progress Administration, and now on the National Register of Historic Places, it is one of the last all-log hangars left in the country. This unique building was once home to two of the world'’s fastest aircraft. The RB-51, a very highly modified P-51 Mustang, held the world’'s fastest piston powered aircraft title for more than a decade. Also based here was a F-104 Starfighter whose record, the world low level speed record, still stands. Most of the aircraft that visit the Red Baron today are a lot slower, but we’'re still happy to offer them great service, and quality fuel, in this unique building.
