Can I bring food from home on an airplane?

It's not the bringing the stuff on the plane... it's bringing it through security, Roxy.
I have never had trouble finding someplace that sold a bagel and yogurt on the other side of security. The restaurants know that people are looking for breakfast! My DH travels quite a bit and believe me, he doesn't skip breakfast, nor does he pack his own stuff.
I abhor Dunkin Donuts. Not the taste of their coffee, but their disgusting advertising, that puts down all kinds of things (like people who speak other languages) and their obvious appeal to specific demographics in a not so subtle way. My drive to work gets interrupted in 2 places by people lined up trying to go through the Dunkin Donuts drive through, who block the road on a major street.

On a recent flight to Reno I was struck by the number and variety of food vendors after going through security. Unless you are going through a very small airport I suspect you won't have much of a problem finding food, but hopefully you can get through with your bagel and cream cheese. All of that is EXPENSIVE, but of course they know they have a captive market.
