With more airlines providing direct flights to many destinations, flights have gotten longer and longer! I recently was on one from Australia to the US and it was 15 hours long! Bum-numbing in my opinion! For me, I'll always look up the airlines' website prior to long flights to check out currently available movies and "schedule" them into my journey. I find that if you treat the flight like an ordinary day, time passes much faster. Block out periods for meals (about 45 minutes with serving and clearing), movies right after meals (which can be sleep inducing!), then a nap. Alternatively, reading a half-finished story book will ease one into sleep as well! On waking, be sure to take a little walk, visit the bathroom etc. to get blood circulating. Talking to your neighbour can also make a flight less mundane. Before you know it, you will be buckled up once again ready for landing! So, how does everyone else kill time on long flights?
