Airline food has long been a gripe for passengers. Not only do you have to pay extra, but it often doesn't even taste good.

With most meals costing around $7 according to ABC, food prices are one of the main concerns with the consummate traveler.

According to a survey conducted by YouGov from March 19 to March 21, the third-highest complaint amongst passengers, at 31 percent, was that "food choices available are too expensive."

Only 7 percent of people purchase foods on airliners, while 22 percent  would apparently rather go hungry and don't buy food on the plane or at the airport.

The second-highest complaint, at 37 percent amongst passengers, was the "very limited options."

Following the price of foods, the "poor quality" of their meal is the next highest complaint at 24 percent.

The biggest problem passengers have with airliners is that they do not offer free food. Forty-two percent of people said that there should be a free, hot meal provided for flights over four hours.

Due to that complaint, one may expect that many passengers would resort to bringing their own homemade foods for the next flight. But according to the survey, only 31 percent of people go that route.

Of the people that bring food onboard, 16 percent purchase food at the airport and 15 percent bring food from outside of the terminal.

Twenty-four percent of people purchase snacks on their flights instead of buying an entire meal.

When asked about the snacks, 73 percent didn't know if the airliner they chose served the best snacks. Delta led the way at a paltry 7 percent and JetBlue came in at 4 percent.
