Being on the actual plane is the most uncomfortable part of the entire experience, for me at least.
Others may disagree, but I'd rather cut an hour from the flight than the entire commute/parking/security/airport waiting. (Assuming conditions on the actual plane were the same.)
The whole experience nowadays is horrible. The airplane is a bus, the airport is a shopping mall. Passengers are just cattle.
Nah, its quite opposite for me. It becomes real chore with small kids on non-short flights, but the thing is - I travel normally only for vacations. Time spent in airports is literally vacation wasted on bureaucracy without even moving, since in ideal situation I would spend 1 minute giving them big luggage, if at all, and stepping in the plane just about to take off. Flying is actually moving me towards the goal, feels more acceptable.
Overall when I started traveling I loved all of it, exciting, new. Now I hate this part as a whole, necessary evil of wasted life to get what I actually want where I actually want.
Unless you pay the sort of money (or more) that supersonic flight would realistically cost. Even without going private, business/first seating (along with expedited service through security, airport clubs, and arranged private car to your hotel) deal with a lot of the issues that many economy travelers have with air travel.
being on the plane is the easy part. put bags up top -- and check the big ones so this is a simple process -- and then buckle-up and snooze.
it's the everything-else part of air travel that is fucking awful.
40+ minutes of security theater even with NEXUS and other fast-passes, lost bags, massive PITA airports, delays, and the hoards of dumb fuckin rubes who have no idea how to travel and need to haul their comically huge carry ons that somehow got through sizing + emotional support chihuahua -- a far cry from even the worst subways I've been on.
Funny, for me it's the opposite. It's uniquely relaxing to be locked in with nothing but a book or some movies (I purposely avoid connecting to the internet during a flight.)
My biggest dilemma is whether to sit in the aisle or window. The former you can get up whenever you want but are bumped by passers by and neighbors exiting the row. Versus being the one doing the disturbing.
And if you can afford business class - where supersonic would be priced - then I mean... The meals are restaurant quality and the full recline?! I hardly want to disembark! The biggest discomfort is the dry sinuses.
But in getting to/from the plane you are cattle moving through a logistical labyrinth with countless possibilities for something to go wrong.
