We have a 7:30 flight this Friday morning do you think getting to the airport by 5:45 will be safe

If you have boarding pass, and carry on luggage you should be ok.

If it's a domestic flight I would arrive 2 hrs early

Personally I prefer to be at the airport early but yes that should be fine because it's a very small airport.

Yes you can

For this airport, that's plenty of time. It usually moves quickly.
