I haven't done the transit at BRU in some time but I can tell you that it is brutal. Depending on where your SN flight parks at terminal A it will be a long walk to catch your CO flight at terminal B. I would expect a transit of anywhere from 60-100 minutes. There is the long walk from the SN terminal to the security check. Then, a good wait there. Then, you have to walk a good distance to the adjoining terminal to catch your CO flight. Anyone else done the BRU transit more recently?
