A couple of tips for those of you who haven't travelled far with kids before.
*Order the kids meal, it is a good sized meal and it gets brought out before everyone else's meals, that way you can get the kids organised and fed before your own meal comes out.
* Don't give them too many sugary snacks, there is not a lot of room to burn of sugar on the plane, LOL!
* Keep them up late the night before the flight, make them tired, it is easier if the kids can sleep on the plane.
* Bring stuff for them to do, colouring-in, journals, etc....I do bring my kids Nintendo's and iPhones but limit the time on them, they are so stimulating they would play them for hours!
* If your airline doesn't supply blankets, bring one, it can be cold on board, the blanket is comforting and can also be used to block light. Also a squishy small pillow is great.
* For younger kids, bring their favourite toy, or whatever helps settle them. Don't even think about trying to cut down on luggage and not bring it! But, don't leave it on the plane!
My kids travel very well, but I have seen many tantrums and unsettled kids on planes, It's not pleasant for anyone, so I say "whatever works" to keeps the kids calm!
