entertaing 2-3yr old on flights

[pumpkin7]

We are going to Holland in June and Lapland in Dec. My ds2 will be 2.9yrs for ist and 3.3yrs for last holiday. He has been on planes before but we have always managed to arrange flights at around the time he has naps so he has always been asleep now however he has ceased having naps and is likely to be awake on both flights.

has anyone got ideas on how to keep a very active child who hates sitting still quiet and entertained on flights.

Play dough, drawing, raisons to eat. DD flew for 3 hours aged 2.6 and she was far better than on car journeys, sat still other than loo visit (and we were potty training at time). Suspect sitting next to mum and dad helped as in car she sits alone.

Thanks Lasvegas. I just worry about him making a lot of noise on the plane and disturbing others.
