All airlines that serve the airport are listed here.
You should get to the airport when your check-in/bag drop opens. Click on your airline to see their opening hours. Even if you've checked in online from home, you'll still have to check in any possible baggage at the airport. If you've checked in online and travel only with hand baggage, go straight to the security checkpoint.
