Pretty much the only difference between when I flew to orlando, compared to back was the food/drinks (water and crackers only on the way back) and the masks. And I was on first class.
Seperation was an empty seat next to you, unless you were traveling with more than one person. They need to skip rows, which they didnt and first class larger seats but was no different than the rest of the plane.
Remember that on the 4th, airlines will require masks at all times, except for children.
Who could be carriers and bounching off the back of your seat and breathing on your head from that whole two feet away.
Just saying.
Oh and TSA had even less lines open, ONE, than normal and moved even slower than ever. Plan for that when travel picks up.
