Yeah. Seemed so much simpler 10+ years ago. That "Shoe Bomber" cunt seemed to be catalyst for the implementation of 2hr delays at security and irritating restrictions on hand luggage.
I used to fly out of London City occasionally and you could arrive 15 mins before take off after online check-in. Even with normal holiday flights from my local regional airport I regularly arrived at airport under an hour before take off, you never had to worry about ludicrous queues eating time. Even if a bit of a queue had built up they'd come and get you out of the queue if your flight take off was imminent.
Nowadays I get a distinct feeling that Airports revel in the delays and stress they cause... they definitely like the idea of travellers kicking around the departure lounge bored witless for a couple of hours and driven to spending money on food, drink and random tat.
I'd already be tired and tetchy getting on the plane, so 15 more hours sat on that plane in the air would be torture.
I admire the engineering of these long-haul planes but the total door-to-door travel experience they bring just isn't for me.
You're right in that in the old days (pre 2001) you could fetch up at an airport much closer to the departure time. In the 1990s I used LHR Terminal 1 quite a bit, and it was advertised as a 10-minute check in for hand baggage only and for domestic and Ireland flights. I put it to the test many times, successfully.
The problem with 'security' is that once some kind of intrusive, time-consuming and labour-intensive process is introduced, there are too many vested interests in keeping it going. It'll be years before we can go back to a 10-minute check-in, and we most likely never will do.
Airport 'security', like Covid 'prevention' measures, is a big business. Employs thousands and earns millions. And you can never entirely prove or even disprove that any of it actually works.
And we only need one more shoe-bomber type of twat, and it'll be two steps back again.
