I'm sure a bunch of folks here have flown, but I haven't seen much discussion, so here's a brief, boring report from my first flights since late February. Short trip, American from Philly to Charlotte and back, both flights fairly full. I paid for 1st class since it was work and the fare was what coach used to be for the same trip.
The top line thought is, this is risky but if people follow the rules, it should work. I didn't see any blatant mask violations. Both airports are well equipped with plexiglass barriers, and the low level of flights creates lots of open gates to distance while you wait for boarding.
What can't be controlled: people will bunch together in the TSA line, and again when it's time to board (the latter is kind of moot, because you'll be sharing a plane with them anyway). Kids will be kids, loud talkers will talk loud, salesman types will try to start conversations, humans have to use the bathroom sometimes.
So a good deal of COVID avoidance is simply luck. I haven't read about plane outbreaks, but then again I don't think any effort is made to contact trace fliers. I'm probably driving anything under 8-9 hours for a while. Curious what other travelers here are thinking...
