How full are SW airlines as of April 14 2020 (Chicago to Denver...earliest flight)? Are all middle seats left empty?
Do most flyers wear masks? Very few people use inair bathrooms? How about spacing in the long check-in lines? Trip not until July 12...hope things calm down by then.

Not sure I understand your question.

Are you asking how full SW Chicago to Denver flights are now, mid April, to predict what it will be like 3mo from now?

With the virus going on RIGHT NOW....are airplanes FULL? Is the middle seat empty NOW? (Chicago to Denver) It may not get much better by July ("some" said it would "get back to normal by Easter which didn't happen.) Looking for the worst...if things stay the same...whats my outlook as of 04/14? Recently Chicago to Denver....most with or w/o masks.

I don't think anyone is keeping track of who is using the bathroom. Most people who are forced to fly during this time are hopefully more concerned with their health.
I personally wouldn't get on a plane any time soon.

The last time I flew (Denver to Chicago) I sat in the last row. Noise wise....I think 2976 people used that back bathrooms. Thats 14 more people that use the bathroom at a 9 inning Cub game!
