Even though the sun is beaming in Ireland, many of us are heading away on summer holidays.

Now, we've already heard some pretty rotten facts about flying, but this latest one has made us feel totally gross.

Why? Because we basically have to use it every time we fly.

According to flight attendants, tray tables carry a serious amount of germs.

Hello Giggles reports that a recent experiment by TravelMath found tray tables to be the dirtiest part of not only a plane, but the airports, too.

A microbiologist collected 26 samples from four flights and five airports and found that tray tables have 2,155 colony-forming bits of bacteria living on them.

While nothing will ever turn us off flying away on holidays, we think we might bring some disinfecting wipes with us on our next plane journey.
