For what it's worth, that's no longer true since 9/11. We have the same security theatre the US has (with the exception that we don't demand TSA locks), our airports have gone all in on upselling you overpriced crap (really, they're better equipped than some malls, it's insane), and Ryanair drove down the bar for "acceptable" behavior to below zero.
I stopped flying via US where possible as the experience was always horrific.
My record time from taxi to gate is 12 minutes at Porto airport.
There’s definitely no excess of security or any theatre. Very vanilla.
European business class for example, is often just a triple economy-row seat and maybe the middle seat is blocked off. This is different from, say, American business, which is not great when comparing globally, but is at least a bigger seat with more seat pitch.
Trains are trendier than ever and the networks are expanding again. Sleeper trains are making a huge comeback and private companies are shaking up the industry with low fares on popular routes.
But yeah I flew through it a few years before it closed, and you could tell that they were struggling to handle the flight workload of the 2010s in an airport built for an earlier, lower flight frequency (and pax per flight) time.
