Yes, you can bring food and drinks onto planes. There may be limits to what you can bring before security, but anything after the security line is fair game.

[tomp]

After security, of course. As long as they earn money on you buying expensive unhealthy food...

But they don't like you bringing food through security, AFAIK. Drinks are completely forbidden, even plain water, except for infants.

[sushantsharma]

Not true. I have taken food several times through security. I am talking about US airports. Drinks, however, are not allowed.

[pwthornton]

I've brought sandwiches, beef jerky, nuts, fruit, etc. through security. Drinks never work.

Just bring an empty bottle and refill it at a tap behind security.
