don't worry. Your kids are old enough to know all happenings . It makes an adventure trip to them.
My two were 8 and 11 when we flew and we packed lots of little activities in our hand luggage that they didn't know about (puzzle books, reading books, a diary each, stickers etc and a new DS game each) everytime they were getting alittle restless we produced a new suprise for them to keep them occupied. It worked a treat!
