Really great flight, smoothest landing in many flights - for sure best this year!

Happy with everything, however, there was a lady having a coughing and sneezing fit in front of me. In this time of corona virus, I think that people in that condition should not travel, but if they do, the staff on the plane should have surgical masks ready to give them and tell them they’ll have to wear it so they don’t infect other passengers nearby.
