I booked a MAD-BRU-FCO connection on Virgin Express for around $50 one way. Sure, the connection is out of the way, but it was cheap. Well, there is a schedule change and my layover in BRU has gone from 2 hours to 4 hours.

And Virgin Express now insists that I will need to recheck my bag once I arrive in Brussels because I am no longer on a legal connection.

So my question is if there is anything interesting I can do in the airport or the surrounding area given a 4 hour transit.
