Not to mention that severe lockdown policies can be put in place at any time.

As far as flying WB, I absolutely loved it. Some absolutely hate it once they get on the fleet. It's not for everyone. In normal times, it goes extremely senior.
And I'll add that the JBLU guys used to say, 'I don't want to fly international'. Until they started flying to LHR.

You're not really seat locked on WBs. You can opt to go to NB CA and the seat lock doesn't apply. There is at least one other way to get out of the seat lock, but no need to get that detailed for this discussion.
