Q: We need to go between Terminal 2A and Terminal 2B of Barcelona Airport. Is there a shuttle bus service between terminals 2A and 2B?
A: The two terminals are only 5 minutes walk away so you really don't need a shuttle bus.
However, if you need to travel between Terminal 1 and Terminal 2 (previously Terminal A, B and C) there is a free shuttle bus service that runs every 7 - 12 minutes between terminals. For more information see our transfers article.
