I've always questioned who would want to fly potentially a very long distance just to go to an Expo. I mean, is it just me who can't even remember when and where the last Expo was?
I think the demand is massively overestimated by the authorities. I guess Covid gives them a huge face saving excuse for the turnout, but even without Covid I just don't think there would ever have been nearly the numbers they are hoping for / planning around.
