I cannot relate to your experience at least in US. I did a lot of flying this summer and have been flying both nationally and internationally over the years but outside the occasional delays due to weather, my experience has been quite pleasant. Even when traveling with luggage, I can generally check them in right outside the airport where I'm dropped off by Uber. Security checks have been straightforward with just the right amount of annoyance in the mix and mobile apps mean that any last minute changes to gates are well communicated in advance. I have found it all really streamlined to be honest.
