Hi, I'm based just near Brussels Nord for a couple of days and have business at the airport on both days, is it simplest to buy a return ticket to the airport and back each day, or is there a multiple journey option I can take? Are there time considerations i.e. peak and off peak?
If it's of any use I currently have a SNIB 10 journey ticket which is unused at this stage, but I suspect this isn't valid on national rail services to the airport. If not, that's fine, I can use it in central Brussels during my stay.
