Travel really is back – the good bits, but also the bad. The airport delays. The flight cancellations. The monumental disintegrations like we saw in Sydney over Easter. It’s not what we missed, exactly, but it does get you thinking, and remembering, the way things have gone in the past. Because if you’ve travelled for any amount of time, to pretty much anywhere in the world, you’ve probably got a story of airport-related drama. We, here, certainly do.
