Bring your own stuff. Nuts, avocados, beef jerkey, fruit, chocolate and the like. Or it maybe a fun time for an intermittent fasting. Actually, it sounds like a terrible time for that to me. But if you're super anal about being strict paleo and don't want to get creative, it may be a great time.

Diabetic meal!

I'm a type 1 diabetic and have have gotten this a few times.. I think it's the best option for paleo/primal eating. You don't need a 'diabetes badge' or anything, just order it when you get your ticket. I remember getting a big piece of meat and a nice salad.

I have found the Gluten Free option to be a great choice when flying. You generally get some type of salad to start, meat, veg and rice or potatoes for mains and then some kind of fruit for dessert. You will probably get some type of GF bread also but no need to eat that!

I would suggest kosher. Might get the best meat source that way. It'll be fresh at least!

The Japanese meal. It will consist mostly of seafood and vegetables with a little bit of beef. There will be some white rice, which if you choose to eat it, is pretty benign. The worst stuff in the meal is the soy based sauces, but if I recall correcly, they are mostly on the side, so you can choose not to eat them. Plus, the Japanese meals are really tasty.

Apparently there is an entire website dedicated to airline food...www.airlinemeals.net Complete with pictures and a menu card archive. According to them, Continental offers gluten-free. In all seriousness, that might be the best way to assess what comes in any of these Muslim, Vegetarian, Japanese, Kosher, or generic meals on a particular airline. The Halal meals seem to involve rice, which at least a trade up from pasta.

Most of the time I'll do a water fast, maybe some tea or coffee (though it tastes horrible on airplanes, IMO). For very long flights it could get uncomfortable though. I fasted once on my way back from Korea for about 30 hours and felt really cold on the plane.

As others have suggested, if you want to eat something, bring things like nuts, dark chocolate or even hard boiled eggs. Canned fish is an option too but the smell may freak out other guests ;)

If they have something for celiacs, that might be better. Cuts out most of the least healthful grains.

Don't do kosher! I did that and got margarine and non dairy creamer and what otherwise looked like the usual sludge-ugh! This was on Air Canada one way and United on the way back, round trip, to Britain.

Well, I'm about to Travel again and this is my experience from my last flight to Canada from Australia on Qantas last year. Qantas serves quite a bit of food. I wasn't sure what meal to book but I booked a Gluten Free meal before leaving as it seemed to be the best option. However a lot of what came was bread substitute in GF options and I didn't eat that. I had a few nuts and some sardines with me but I was hungry most of the time. Plus I had another internal flight from LA to Vancouver to deal with with no food nor time to buy anything from the airport (LAX is a zoo at the best of time and going through customs - can someone tell me why I have to go through customs in the US if I'm simply catching a flight to Canada- which is interminable, then changing terminals and going through security, queueing for the loo and then going to your gate will take the full 3 hour transit time).

So as soon as I got to Canada I changed my return flight meal option for a diabetic meal which was probably better overall. I mean really what I would like is a whole food option with no processed carbs and no grains, just some protein option, some veggies, some root vegetables and ideally some salad and nuts but ok I'm dreaming. Now it's that time of the year when I do this whole moving to Canada for 5 months again in three weeks and this time flying to Montreal first (via Sydney and Vancouver - got my lesson going through LA last year) and then onto Vancouver ten days later. I'm flying Air Canada and wondering if anyone has experience with the special meals on Air Canada, specifically the Gluten Free options and Diabetic meals unless you have a better suggestion.
Many thanks
