My friend Lillian was just talking about flying to Melbourne from London via Hong Kong with 2 young children over this holiday…Make sure you carry a pack of No Jet Lag pills in your travel bag!
Made in New Zealand, they are a homeopathic remedy against travel fatigue, a mix of arnica, wild chamomile, daisy and other little good things for the experienced traveller. They are good for the whole family, starting at 1 year old, and work really well if you take them as indicated, ie. every 2hours (every 4hours for children) during the flight, and at take off and landing. One pack is sufficient for 50 hours of flying and they are quite aptly called the perfect travel companion. I usually stock up on those at Bigelow in NY (they sell online) but check out the website for a complete list of points of sale.
