Update on the showers at Brussels Airport. The showers in Terminal B are under construction now. Not sure when they will be open again
Today, after
running 7 miles through Brussels in between flights, I came back to find no showers available in Terminal B - for any loungers.
I had to take the bus to Terminal T, and shower at the Sunrise Lounge there (Star Alliance Gold has access, not sure about others), then bus back. No problems in doing so, but it does add 20 minutes to get there/back and the lounge attendant did wonder why I was in T if I was flying out of B.
