A couple of other tips for flying are:
- to take nappy change stuff in small ziploc bags so that you don't have to take a big change bag into the loo. i take a few of them so they are always handy
- have more bottles than you think you need as it's stressful if you think you're going to run out
- use huggies super dry nappies or similar so they don't get so wet
- get one of those sleeping bags with holes in for the seatbelt so you can strap them into car/plane etc. easily
