When I’m flying on one of those so-last-century planes that doesn’t have a screen mounted in the seat in front of me (which is often for flights out of Adelaide), and when I’ve already read the week’s Speccie (sans the books, arts and bridge sections), my practice is to plug my headphones into my armrest, tune to the Smile High Club on radio Q, and see whether they’ve changed the comedy playlist since the last time I was stuck in a plane without a television.
