How will we ever address travel requirements in the future for people with tickets and have viral symptoms? This may sound like a stupid question with Covid, but at some point we have to reach the post-covid world and some ( hopefully most soon) viruses are not serious and people do need to get to their destinations in a timely fashion. Nobody with the common cold should be delayed for days that could impact their employment or simply not being able to get home. Will people denied boarding be able to re-book at no extra cost? I think of the implications of travel and coming down with a virus leaving you stuck high and dry somewhere. I believe that most people have picked up a virus while traveling at some point in their lives.
