Frontier Airlines BCN Terminal is based at Barcelona El Prat Airport (BCN), Terminal 2. Several low-cost airlines, including Frontier, are served by this terminal, providing travelers on a tight budget with a simplified experience. Travelers on Frontier flights can check in at the desks designated for that purpose, go through security, and then go to the departure gates. Cafes, stores, and lounges are among the basic facilities available in Terminal 2. Arriving early in advance is crucial for passengers because security lines can get long during busy periods. The terminal has convenient access to city transportation and is well-connected to the rest of the airport.
