I recently brought In-n-Out in my carry-on luggage for my family in Washington. Best Christmas Eve dinner ever.
Ha. Did you take any precautions to keep the food fresh and not-messy? Do tell.
Well, I had 6 double-double animal styles (double-doubles animal style?) in one of their brown boxes. I took care to keep my laptop bag horizontal as much as possible. By the time I got home, the bottom of the box was pretty soggy. The lettuce was a little wilted, but we re-heated the burgers in the microwave and they were pretty darn good. I would say about a 15% reduction in quality.
