What time does the airport actually open its doors for a 5:50 am flight

I love the small airport but in winter flights get canceled to easy I would love to see airport expansion!!!! To handle weather and flight options!!

The doors are rarely open before 5am. I wouldn't expect to make it out on time during the winter. It's my biggest complaint with this airport. They never deice the plane prior to boarding times, which then puts the morning flight about 45mins late every time. Don't make short layovers!
