Passagerterminalen 10, 7190 Billund, Denmark
Clean, modern, cozy, nice places to grab a bite. We had to wait many hours but it wasn't their fault. The only negative of the whole experience was the liquid control, since they made me throw away things that didn't fit in the 1L bag. I've been to 3 other countries with the same amount, and nothing happened.
I loved this airport - it was small and cozy. Arriving: Buses and taxi were just outside the building, very easy to find. Departing: It took us 1 minute to pass security control check, 2-3 minutes to reach gates. I arrived 5 minutes before boarding start and was very afraid to miss my flight but everything went so fast and smooth.
Very nice airport. Easy to go through
Be aware that they enforce restrictions on liquids in carry on luggage. All liquids, creams, etc MUST fit in a small one litre plastic bag which MUST then be sealed. Anything that does not fit they will confiscate. "European rules" apparently. I travel throughout Europe every month and this is the first time this rule has been enforced by security at an airport!
ATM (the only one) is located in before security check, so if you want to withdraw a cash while waiting for connecting flight, you have to go outside and then back through security. Being that said - It's a small airport with everything (duty-free, gates, restaurants, exchange) in sight, thus easy to find almost all you need. Seems quiet and efficient.
