Transited NCL -BRU - DME the other week. No hurry for my DME flight, but there was a couple on the inbound jungle-jet going to somewhere in Germany. Hostie made sure we all stayed seated until they were off first and into a waiting minibus c/w hold baggage straight across the ramp to the outbound. (And the pax were in the rear of the jungle jet, so probably B-lite).
Overall, I was quite impressed with the whole Brussels airlines experience. Only slight critism was coming back through Brussels in the evening from non-schengen to non-schengen, we were bussed off the DME to the non-schengen bus terminal in the middle of the pier, but the escalators and lifts upstairs were closed off, so it was walk all the way back to the main wing, then a walk back upstairs to the non-schengen bus terminal. I would not have wanted to be in a hurry for that one !
