Please get there early
The lines for TSA security checkpoint opens at 5am. The last time I was leaving for an early flight (pre-covid) there was a line around the corner. This is a small airport and they only have 2-3 TSA check ins. I'd recommend getting to the airport before they open so you're not stuck in a line. I'm sorry to give inconvenient advise but it's better to get on your flight then be left at the TSA checkpoint still waiting. If it's any consolation, there is a DD in the terminal area to grab coffee and breakfast.
