To be extra safe, the CUNY researchers advised people never to drink water onboard a plane that does not come from a sealed bottle. They also said passengers should not drink coffee or tea brewed on their flight, and that they should even use hand sanitizer instead of washing their hands with onboard water.
"All drinks with sugar, caffeine, or alcohol should be avoided to limit dehydration, and water should be the only drink choice during flights."
It should come as no surprise that the healthiest thing to drink on a plane is water, which also happens to be the healthiest thing to drink on land. Inside an airplane cabin, the air is extremely dry, putting you at heightened risk of dehydration. That can lead to nausea, headaches, and other unpleasant outcomes.
Anton Radchenko, Travel expert and founder of AirAdvisor, said that the most important tip he tells people is to "avoid drinking plane water" – no matter whether it's in cold or hot drinks. There are many reasons for this, but the main is that the "in-flight tap water systems are rarely cleaned".
You can take any food and drink you like in your hand luggage, as long as there are no hot drinks.
If containers are larger than 3.4 ounces (100 ml), they won't be allowed through security, and the security officer will discard them. However, you can bring an empty reusable water bottle of any size through security and fill it up after you've gone through the checkpoint.
Travelers are allowed to bring food through airport security. However, you should remove any food and snacks from your carry-on bag, along with your bagged liquids, to be screened separately.
"To be extra safe," the study concludes, travelers should not drink coffee or tea onboard, and "never drink any water onboard that isn't in a sealed bottle." After using the bathroom, the study also suggests travelers use hand-sanitizer.
Yes, it is safe to drink coffee, tea, alcohol and water on airplanes. According to various flight attendants who have been working from various three to five-star international airlines.

Choose a calming drink like camomile or peppermint tea to help you relax, or even just water. Have a light meal before your flight to help settle your stomach, but try not to overdo it.
“While plain water is best for staying hydrated, other drinks and foods can help, too,” says Theunissen. “Fruit and vegetable juices, milk and herbal teas add to the amount of water you get each day.” Consider bringing your own herbal tea bags while flying.
Grosskopf said that a bloody mary, gin and tonic, Moscow mule, and a mimosa are all “safe bets” on flights. She also noted that a glass of wine can be refreshing if you're not into spirits. These are a few cocktails that are particularly popular with travelers.
This is because the air pressure is keeping the Coke in the can. It makes pouring the Diet Coke very controllable and reduces the chances of spilling or overflow." The air on a plane is much drier than what it is on the ground, meaning consuming fizzy drinks as well as alcohol can leave you feeling unwell.
Let go of the legumes
All legumes contain a sugar called oligosaccharide that the human body finds hard to break down completely; this may result in bloating and discomfort, and you guessed it … more gas! If you can't avoid them completely, try eating them with a lot of restraint.
According to a 2016 study by a group of Cornell researchers published in the Journal of Experimental Psychology: Human Perception and Performance, tomato juice, AKA the main ingredient in a Bloody Mary, tastes better in the air due to the noise level on an airplane, which influences a human's perception of taste.
On drinks: Only order beverages that come in a can or a bottle, Kamalani strongly suggests. That's because anything that uses boiled water—which includes coffee and tea—will be made with water stored in the plane's tanks, and those tanks, she says, are never cleaned. The water is "disgusting," she says.
Yes, the Transportation Security Administration (TSA) will allow you to bring ground coffee through airport security in your carry-on baggage. It's best to limit the amount of ground coffee you pack in your carry-on to containers of 12 ounces (350 ml) or less.
If you are flying to the US, there is a limit of 350g (12 oz) on powdered items that may travel in your hand baggage, such as cosmetics, spices, powdered milk, flour, sugar, coffee or similar. Passengers who wish to travel with more than this limit must pack these items into their hold baggage.
That same question has been asked time and time again on social media by disgruntled flyers. Paying for water on a flight isn't illegal. The answer is, it's not illegal. Turns out the airlines are not obligated to supply free drinking water in the same way they are not obliged to offer free food.
Whereas larger airlines often hire dedicated cabin cleaners to tackle the aircraft between guests, “Generally on low-cost carriers, the flight attendants will have to clean the planes themselves,” says Catrina McGrail, a former flight attendant and creator of the 24 Hours Layover travel blog.
Checked Bags: Yes
Solid food items (not liquids or gels) can be transported in either your carry-on or checked bags. Liquid or gel food items larger than 3.4 oz are not allowed in carry-on bags and should be placed in your checked bags if possible.
In short, the 3-1-1 rule is: Each liquid you bring through the TSA checkpoint must be in a 3.4-ounce or smaller container ("3"), all containers must be placed inside one clear quart-size plastic bag ("1") and each passenger is only allowed one plastic bag ("1").
The items must be placed in a 20cm x 20cm zip lock bag. Only one zip lock bag is allowed per passenger, with exceptions for carers who may carry the bag/s for people in their care, including children. Empty containers such as flasks or water bottles may be carried through the screening point.
