I cannot really offer much more advice than is given here...just do something you have already done - she wont know even if you do - it will be new to her...
Every time my wife gets in a plane with me she goes to sleep....
miffs me right off....I mean - whats the point in flying eh? I could take her for a 20mins drive into oxford and get the same result...
argh..
I must say that winds me up the most - passengers who fall asleep @ £xxx/hr....when there is an AMAZING world outside to be gawped @...lets face it - Im an instructor 100's of hours - starting to give up counting...and I am *still* enjoying the view (when I can snatch it)...only the other day I was up with a student and the wind was rippling through the barley fields - truely amazing - moreso than crop circles...
So I guess my real advice is make sure you keep prodding her to make sure she stays awake!!!!!
As for my first flight after test....local area (well 1:45 over my house etc...two weeks later I did my 300nm trip to Norwich & then leicester...which was a blast as @ Norwich I was marshalled in to park up next to a B737 - all for the princely sum of £12.50 if I recall!!!!
So I guess the bottom line is...enjoy it...
