Helicopter time dosen't count for most airlines, even if it was a multi-engine, tandem rotor helicopter. Finish flight school and learn your skills as a Warrant Officer first. (spelling does count) Fixed Wing transitions for Active Duty Warrant Officers are possible but they are merit based, you can apply after 2 to 3 years depending on the annual message from DA. If you’re a Reserve Component Warrant Officer you can fly airplanes if you can get in the unit and they have a slot for you. The majority of Army fixed wing pilots are Reserve Component. One tip, don't mention to anyone that you only came into the Army so you could find a way to work for an airline, that will pi$$ them off! Army Aviation has the best helicopter pilots in the world; stay highly motivated and you will have the best time of your life!
