SAS offers two service classes for intra-European flights, an economy class called "SAS Go" and a premium economy class called "SAS Plus". SAS Plus tickets are refundable, and include a meal, a double checked-in baggage allowance, and access to lounges and fast track immigration/security at the airport. The SAS Plus passengers are seated at the front of the aircraft but the seats there are otherwise the same as the SAS Go seats. The two-class system was introduced in June 2013, when business class was eliminated from intra-European flights
