Or not, as we’ve had a late swap to a non-CS 77W. This left me without an assigned seat come check-in time last night (still said 7A, which doesn’t exist). Figured I’d leave it overnight and see what happened as J was completely full, and there are fewer seats on the non-CS planes.

Woke up just now to a seat change notification and I’m now in 3A - so that’s worked out well!
