We do it all the time, even if we are only going for several hours and I am referring to our own aircraft the Cessna 172.
I will usually take:
1-ham and cheese sandwhich
2- two salted green onions
3-a small bottle of water
4-apple or some other fresh fruit
The old girl will take:
1-sandwhich other than ham and cheese
2-pickles
3-a sweet like a piece of pie or cake
4-cheese
5-small bottle of water
We share a large thermos of tea, celery and carrot sticks.
We have been doing this for years and we find it saves on pit stops and is quite enjoyable.
A sort of flying picnic.
The aeroplane also has an emergency ration kit as most of the area we fly over is sparse. I change the kit once a year.
One of the things we do is I pack her snack/lunch and do not tell her what she is getting and she does the same for me. She does know I love my green onions though.
Just one of the little things that seems to make life go smoother.
