I don't mind the act of flying (climate-change aside) but I really dislike airports and the palaver that each end of the flight necessitates.
I am also reminded, today, of the epic class system that exists whereby, on this full flight, those in "groups 5 & 6" (cattle-class) who have brought wheely things for the cabin are suddenly required to surrender them to go in the hold because the flight is full.
Lastly, why does it take almost an hour to board a plane?! It's not even a very big one (A320)!
