I arrived in Mexico City after a predictably exhausting fifteen hours of missed flights, ticket counter lines, delayed flights, bag mishaps, backing and forthing across airports, and bad weather. It’s amazing how quickly things can go from peachy to absolutely nightmarish when travelling by air, particularly when connecting flights are involved.

And yet — after being in a state of “almost there” for so long, stepping through airport doors to find an underpass and a queue of bleary-eyed travellers waiting for taxis was extraordinarily satisfying.
