They may be looking at squeezing a SOU-Belfast-SOU in the gap where the aircraft currently sits at SOU after arriving from ANR so Belfast based passengers can connect to and from Antwerp. VLM do seem to be linking quite a few major ports (SOU, ANR, HAM, RTM) so it may not be to far fetched to see the likes of Belfast and possibly Liverpool added in to future. It is worth pointing out that the BFS wiki page has been edited in this manner before with various 'wishful thinking' airlines and routes so take the information with a large handful of salt.
