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.
I try to find absurd humor in counting the different steps that I had to go through from leaving my house to getting on the plane. Or analyzing the legibility & usability of the systems. Or just being proud of myself for being able to be so patient and let it all go. Sometimes you can even strike up a good conversation with a stranger. But with kids, oof, yeah... :-)
I expected that others would have opposing experiences and tried to reflect that in my comment. People are different sizes, flying different class, frequenting different airports, traveling with families or solo, for longer or shorter periods of time, more or less luggage, etc. So of course it won't be universal.
My main point is that all time is not created equal, that it matters WHERE you shave the minutes/hours off, not just what percent of overall travel time is removed. And while we disagree on how to apply this, we seem to agree on that main point.
