The main airport for Roskilde is Copenhagen Airport which can be reached in about 40 minutes by train. Since April 1973, there has also been the small local Roskilde Airport, serving light aircraft for training, taxi, and flight instruction. There are plans to expand it for use by larger aircraft, possibly including discount international flights. The plans were approved, but lack of commitment from any carriers has postponed progress. The airport currently handles up to 100,000 operations (flights) per year, most of which are light aircraft operations associated with school flights.
