Yeah, OP has not known true suffering.
Although smaller airports can be fun or exciting too. I departed from a very small airport to go to amsterdam en route to somewhere else, and the plane was parked outside the gate as if it was a fucking car. All 4 gates were next to each other, and I think there was more than 1 plane there. So I multiple checked that I was in the right fucking place and plane, otherwise the wrong plane was the next one along.
I know someone who much prefers smaller airports because it's harder to get lost in. Our medium sized city's smaller airport is nice for her, and we had a hell of a time in madrid due to having to take a train in the airport for connecting flights, and running from one end of the new istanbul airport to the other to catch the connecting flight was hell.
I've been through Heathrow, and I don't see the horridness. In fact, I often preferred to go through heathrow since it has the picadilly line connection instead of fucking about with national rail like the other ones.
