I was at Brussels airport yesterday and was surprised that gates information are not published until (exactly) 15 minutes before boarding time. The panel says
Relax, gate info at 16:20
So I went to the gate as soon as it was known, and the aircraft was already there, connected to the passenger boarding bridge. Meaning the gate was definitely known for some time before it is published!
Then I queried some information from the staff ; and indeed, gate information is always only published 15 minutes before boarding time.
The only reason I could think of is BRU wants people to spend time in shops...
Is there another reason for not informing gate details earlier? (which is a bit annoying)
