Gone are the days of airlines leaving middle seats empty, of planes flying with few people, of nearly empty airports. Business travel may not be back, in-person conferences may be the exception rather than the norm, but the airports and airplanes are full.
The trip going out to Reno, both flights (we connected in Dallas) filled every seat. On one of them the gate agent came on looking for empty seats she could fill. The gate areas were packed with people. On the flight back, I lucked out with empty middle seats on both flights, but the planes were 90% or more at capacity - on a weekend that American Airlines was having schedule problems, they cancelled 18% of their schedule that day mostly due to crew shortages.
There is no "food for sale" in coach. No alcohol in coach (no big difference for me, I seldom drink when I am flying.)
The photo above was taken DFW, we ended up with four hours between flights. I found the manspreading and the stop the spread sign to be a delightful contrast. I do enjoy an empty middle seat and being able to spread out a little.
