British Airways OSL Terminal is easy and efficient at the Oslo Gardermoen (OSL) terminal. Wait times are reduced by streamlining security and check-in. With plenty of seats, free refreshments, and drinks, the lounge is stylish and cozy. The helpful and amiable staff further enhances the pleasant experience. Even though the station is tidy and well-run, there is room for a few more restaurants and shops. An excellent and stress-free airport experience all around.
