Lufthansa is cancelling ~ 50% of its flights and Germany has been grouped into the high risk countries with the Corona virus epidemic. Some countries are implementing travel restrictions and hospitals are putting up signs and cameras to prevent theft of desinfectants and masks.
Display space is filthy expensive for most if not all aviation exhibitions and as someone who has done the PPU calculations for events, in determining wether or not to display products to a large number of leisurely strolling onlookers, I can see event organizers trapped between a rock and a hard place.
The internet is the better marketplace anyways, so why not shift the suddenly remaining event- clowning budget into online advertising campaigns. I am glad to have cancelled AERO 2020 during the drive home from AERO 2019.
Many many of my colleagues had booked rooms in April 2019, planning their stays right down to the restaurants they’re planning to eat out in.
Those poor souls are kindly advised that the Bodensee area has more to offer than AERO. Its a beautiful area down there and Friedrichshafen is nice without thousands of driving-challenged aviators and aviatrixes fighting for their spot ahead of one.
