It can sometimes be a struggle to find a vegan option on an American airline. I was surprised that my flights in SE Asia on both Singapore and Silk Air both offered numerous vegan options, from Asian vegan to American vegan, and also offered a RAW FOOD option! Cabin air pressure in flight is lower than air pressure at sea level, which means we have less oxygen being carried in our blood. Cabin pressure makes our digestion more challenging due to a 30% increase in gases trapped in our body. And, flying is dehydrating. I try to drink a liter of water for every hour of flight time. I say a raw food platter should be served to everyone on every flight. It's full of water, oxygen, and easy on the digestion. This isn't rocket science, but simply common sense. Hopefully, this vegan and raw meal also helps offset my carbon emissions a little bit....
