Snack
Airplanes and airports always make me crave salty snacks. When I was flying to and from the Phillipines a few years ago, finding anything that satisfied my craving was difficult. There was a lot of chocolate and candy, but chips and nachos proved difficult to find particularly in the Hong Kong airport. Neither salt and vinegar fish crackers nor lobster flavoured potato sticks felt like the right choice. I don't remember if I found anything there, but on my way home, in the Manilla airport, I did find Nacho Pizza flavoured potato crisps. They weren't particularly noteworthy, so probably exactly what I needed. (Well, they probably didn't help my blood pressure, but that was before I had that diagnosed and there were worse things for my blood pressure on that trip.)
