About a week and a half ago I wrote that if you must travel now, you should consider turning down the first class upgrade. There’s not much service or food to speak of, so you really just get a bigger seat. But first class is more full than coach. You’ll be more comfortable – and more socially distanced – by sitting in back and spreading out in your own row.
American Airlines has basically taken this approach and made it mandatory for their employees who as traveling as non-revenue passengers. “Nonrevs” can no longer fly first class on narrowbody aircraft.
