I speculate we’ll see more airspace closures once countries give enough time to avoid stranding their nationals.
I wonder if, say, Germany, waited until its planes had to chance to land before closing their airspace, while other countries/companies, like Norwegian got caught by surprise.
The closest thing to a German 737 MAX are 15 owned by TUI, which seem to all be based in the UK.
There hasn't been much fleet renewal in the German market in recent years, just lots of consolidation (it's actually a bit of a lottery to buy a ticket in advance due to all the bankruptcies)

Convenience over safety?
Total speculation on my part.
