it depends on the ailine i'm flying with.
when i know there will be food served on the plane i don't bother packing food.
the new cheap airlines have really REALLY crappy food for sale in the airplane, so i usually pack my meal when i travel with them.

I know when I was on my long flights to Europe and Fiji I brought food with me...well what I was allowed to bring.
It helps me feel normal when I'm a million miles up there!

There are actually a couple of airlines whose food I enjoy when I travel internationally but domestically I can't say the same thing (at least not currently). My fiance and I will be traveling cross-country on T-giving day with homemade brunch kits in hand.

I was JUST on an airplane yesterday, returning from Vegas, and made sure to pack a banana and apple, plus an energy bar. The flight actually wound up having these little boxes with a couple items inside - I skipped the beef jerkey and cheese/mini breaksticks but was pleased to find 100-calories packs of Chips Ahoy. I've never tried these little packs but love 'em - great idea for portion control.

Also, my all-time favorite food for airplanes - two McDonalds Fruit & Yogurt parfaits. Delicious, not bad for you and they stay cold for hours, so I can buy 'em, sleep for the first hour of the flight and then wake up to a tasty treat from (gasp) Mickey Ds!

Just snacks...

i always eat what the plane provides

I pig out on my layover, LOL.

the plane always has food.
why would i bring anything?
its free too, theres always a snack on short flights and meals on longer flights.

bringing food is just dumb, no offense

I usually always bring an apple or two. I'm still mad about not being able to bring my own water. I always used to bring at least two water bottles, but now my only option is to spend a fortune buying it at the airport. Boo.

Also, looking at all the unfit, unhealthy people that are at the airport usually helps me skip the McDonalds line, the convenience store treats and the eating of the high cal snack on board. I just feel so much better being able to look at all these people and eat my healthy apple (or banana or whatever).

not all flights have food. most only provide drinks and tiny bag of pretzels. I always bring a small sandwich or snack. When I'm traveling with others, I bring more but when it's just me I stick to small, bite sized things. I tend to feel bad if I'm eating something big infront of starved people.

I used to until the most recent security threat with liquids. I've been too afraid to try and bring food, only to have it tossed.

I always bring apples, baggies of baby carrots, baggies of sunflower seeds and nuts, and gum. Most flights I've ever been on do have food, but it's usually garbage. I'd rather eat an apple than some crappy processed cheese and crackers or chips or whatever. And if there is an inflight meal, I always ask for the vegetarian meal because it's usually healthier.

I like to be in control of what I eat, so I bring my own food on board.

I always bring a bottle of water, and I'll pack a Luna bar just in case. But I prefer to eat my meals in a more pleasant environment than on a plane or in an airport.

I always grab something in the airport before I get on.

When I flew to Alberta last summer we had an early morning flight which connected to a late morning flight. So I had a non-fat vanilla latte for the first part, and then I grabbed a meal at the connecting airport.

I was pleased with the healthy options at the airport, there were real vegetables!

I take snack things I know will pass security: trail mix, nuts, protein bars, fruit. I'm upset about not being able to bring a bottle of water through anymore, though.
