Black Swan:
It will all be a moot point if Coronavirus takes hold in Europe and panic sets in... The second fearmongering takes over and corporates stop sending people on planes then airlines will be going bust quicker than you can hail a London cab - Fly maybe will probably go first, but the longer it goes on and is more public then it will even start to hurt the LCC's as the summer holiday bookings will just not be there - UK staycation coming to a town near you.. get those fingers tapping on airbnb... and oooh and then even more good news... a recession and a hard brexit - what fun!
