Most of these is why I prefer travelling from B-tier smaller airports. Security queues are usually shorter, there's few to no shops on the other end and you can go from airport entrance to gate in less than 15 minutes if only bringing carry-on, which is not difficult to do with a bit of discipline. It also means you can arrive at the airport an hour - hour and a half before departure. Of course that isn't always an option but I'm lucky that my most common travel route is between a B-tier medium-sized European airport and a tiny airport that sees less than 2 commercial planes a day on average.
