The amount of crap that a passenger endures from the moment the idea of flying somewhere crosses their mind, through:
planning,
booking,
packing,
getting to the airport,
getting through the airport,
the boarding process,
enduring one's fellow passengers,
getting out through the airport at the far end,
transferring to one's final destination,
checking in to the accommodation....
...and assuming that all goes well throughout, it's quite surprising that so many people still do it.
In my case, having arrived at a stage in life where I have the time and the money to travel at will, all I lack is the will.
In fact, I usually fall at the first hurdle - the airlines taking the piss with their "dynamic pricing". A marketing triumph for the aviation industry no doubt but I can't be the only one who increasingly finds the motivation to take a holiday by car or train on their home landmass. Life's too short (and getting shorter every day) to waste it on air travel.
