Sitting next to an upset child is every airline passenger's worst fear, but a YouTube video taken by a passenger on a Lufthansa flight from Germany to New York in August 2017 takes those fears to another level.

The Daily Mail first reported the video, which shows a child yelling, climbing on a seat, and running through the aisles. The video indicates that the child was disruptive throughout the eight-hour flight.

"That was a nightmare — eight hours of screaming," a person can be heard saying at the end of the video.

12 PHOTOS 12 tips that can get you through the airport as quickly as possible See Gallery 12 tips that can get you through the airport as quickly as possible Apply for TSA PreCheck status Signing up for TSA PreCheck or Global Entry can help save you valuable time, as you can keep your shoes, belts, and light jackets on as you go through security. You also don't have to remove your laptop or any liquids from your bag. It will help get you through an expedited line over Thanksgiving weekend as well as each time you travel afterward, making it a valuable investment. Check in ahead of time. Give yourself as few tasks to do at the airport as possible. Instead of waiting to pick up your boarding pass, check in ahead of time, either online or on your phone. You can go paperless at most airport and use an electronic pass on your phone to board. Download your airline's app. American Airlines, Southwest Airlines, Delta Air Lines, United Airlines, and British Airways are just a few of the airlines that have developed mobile apps to give travelers real-time information on flight delays and gate changes. That way, if your gate has changed and you're short on time, you’ll know before you even get to the airport. Wear slippers. If you're going to have to take your shoes off at security, make them easy ones to remove. Slippers are a good choice because they'll keep you warm and cozy on your flight without taking too much time to remove at security. Buy a TSA-approved laptop bag. Certain laptop bags are specially designed to be approved through TSA security, meaning you won't have to take your laptop out separately when passing through. Simple cases like this one from Case Logic ($27) are perfectly reasonable. If you're bringing gifts, leave them unwrapped. If you're exchanging gifts over the holidays, ship them ahead of time to avoid having to take them through the airport. Or if you're going to bring them with you, leave them unwrapped, as TSA agents may have to unwrap them. "Wrapped gifts are allowed, but we recommend waiting until you land to wrap them," it says on the TSA's official blog. "If there's something in the gift that needs to be inspected, we may have to open it … It also slows down the line for everybody else when we have to do this." Pack shoes foot-to-toe at the bottom of your bag. Packing your shoes in the bottom of your bag will help to put some weight on the wheels of your luggage and make it easier to remain balanced, especially if you're rushing to your gate. Arrive early. This one seems like common sense, but make sure you leave yourself more time than usual during holiday travels. Brian Ek, a travel expert for Priceline.com, told Fox News that he encourages fliers to arrive at least two hours before their domestic flight and three hours for international flights that are leaving early in the morning or late at night. For normal business-hour flights, he recommends giving yourself another 30 to 45 minutes, just to be on the safe side. Keep a bag of essential items ready to go. Skip the time it would take to transfer your shampoo into a 3.4-ounce bottle and have a bag of toiletries ready to go. Grab samples of your favorite products, or get travel-size toiletries and store them in one bag so you can simply grab it and go each time you pack. Have a booking app set up on your phone. Canceled flights are an unfortunate reality when traveling during the holidays. To help ensure you get the best place to sleep if this does happen, have a booking app set up on your phone so that you can make last-minute hotel reservations or rent a car. If your flight does get canceled, take advantage of your time and start calling the airline over the phone while you wait in line. Look for lines toward your left. According to CNN, looking for lines toward your left side can help you spot the one that's shorter. Studies show that Americans are more likely to turn right than left when entering a building. If your flight is delayed, relax at an airport lounge. Even if you're flying economy, it doesn't mean you can't access airport lounges. Most lounges sell day passes so that anyone can experience last-minute pampering and relaxation. You can also get a Priority Pass, which gives you access to more than 1,000 airport lounges around the world. Finally, check your credit card to see whether or not it gives you lounge access. Some, like American Express Platinum, have access to Delta and Centurion lounges. Up Next See Gallery Discover More Like This HIDE CAPTION SHOW CAPTION of SEE ALL BACK TO SLIDE
