I was aware of construction work around stand 62 and where the mail tent was, but i was referring to the closure on stand 6 by the terminal as i knew they would be starting work there and in the undercroft to support the road above when they expand the terminal to build for new gates and shops above the road way where the coaches park but i dont think they have started there yet. As reguarding the BY flight qs, i was not at work at the time of this flight and i cannot give you the real reason for the delay, but the crew offloading the aircraft could of been pushing one of the easyjet's you mentioned were being pushed at the time of the aircraft on the ground.
Sounds like Hamburg is going to be a popular place from BRS both with lesiure passengers and airbus employees flighting between HAM & BRE, the german market is starting to expand now from BRS hopefully the french regional will follow soon instead of just CDG & TLS etc
