Boarding was called for all passengers with no priority boarding or anything like that. It was a short work to the plane ... again with distance (unless the guy in front of you suddenly stops). Upon entering the canbin the purser handed out a bottle of still water to all passengers. Don't know if there were any extras for the few passengers in business class. Everybody had a mandatory free neighboring seat and we were asked to sit at the window. While this provided good space to the other passenger across the aisle you still had a passenger in front and behind you. About 30-40% were wearing masks (which was not mandatory at that time). As I got a seat in the emergency exit row there was a bit more space for me ... but in the end a CRJ900 is not a big plane.
Flight itself was totally uneventful. While taxing to the runway it was a big like passing the offerings of a pre-owned jet dealership (lots of LH gear on offer today...). Due to very little air traffic the flight arrived quite a bit early to Hamburg where we parked at a gate at the main terminal but walked the few meters into the building. Inside HAM was pretty much the same as in MUC. Lots of empty space.
My first thing after getting of the plane was to wash my hands (I did that also after arriving by train in MUC and after passing security) Interestingly only 2 or 3 other passengers did the same. And if you think the departure board showed more activity than MUC - look again: It covers the next two days as well.
Deserted airport right after exiting baggage claim. The upstairs to Terminal 1 checkin hall and out to the curbside where Was picked up. Definitely not a problem with parking.
