PHILADELPHIA (CBS) – If you are someone who travels on a regular basis you probably grab meals at the airport…maybe a significant number of meals. I have good news. Airport food has improved from previous years.

At least one vegetarian entree that is low in fat, high in fiber and cholesterol-free can be found in just about every airport. Over the years, the top airport food has often been found at Chicago’s O’Hare airport.

The good news is that there is not as big of a difference from airport to airport anymore and the choices available are more varied. But, remember that there are still plenty of bad options as well. It still comes down to making good choices.
