Do Lufthansa planes have power outlets?
First, Lufthansa has no power plugs in economy class for larger devices, only a USB port. … When I do fly economy class it is usually on United and every single United mainline aircraft now offers power ports (at least two for every three seats). My laptop was fully charged, but that’s only 3-4 hours.
Do Lufthansa planes have TVs?
All Lufthansa Airbus A380 aeroplanes all have MediaWorld with seatback TVs that have Audio-Video-On-Demand (AVOD) screens in all classes including economy. Business class has very good TV screens, at 10.4 inches.
Can I charge my phone on a plane?
You can take all plug-in phone chargers with you in your carry-on or checked bags with ease as they do not contain any form of battery and, therefore, do not present any danger. Typically, you will not be able to use this type of charger onboard as most airplanes do not have power sockets.
Outlets for everyone on Amtrak
Amtrak might be the most juiced-up way to travel. Unlike planes, which tend to be hit-or-miss when it comes to outlets, Amtrak trains have outlets throughout the cars. On most trains, every seat has its own outlet, even in unreserved coach seating.

There’s a catch, though. In coach seating, the outlets are located next to the window. Seats are arranged in pairs. Each pair of seats has two outlets, one for each passenger. That makes things tricky if you’re in the aisle seat. Not only will you have to lean over your seatmate to reach the plug, but your shorter charger cables might not even reach all the way from your seat to the plug. And there’s also the possibility that you’ll find yourself seated next to someone who decides to hog both of the outlets with little concern for you. Reserve a window seat if you’re concerned about outlet access.
Business class is usually set up the same way as coach. Things are a little easier in first class. There, each seat is usually equipped with its own individual outlet. Your train might even have outlets in other public spaces, like the observation car (if there is one).
Amtrak’s plugs are standard 120-volt American outlets with three-pronged B sockets. If you’re using electronics from a country that uses different sockets, bring your own converter.
Check TSA regulationsGetty Images
The transportation security administration has a lot of regulations that passengers have to follow in order to fly. And while some are not intuitive — in some cases, they may seem absurd — it’s still critical to adhere to them.
For example, you cannot bring liquids over 3.4 ounces with you through security. I’ve seen countless beverages tossed by TSA officials to the chagrin of unknowing passengers. If you’re going to bring liquids over 3.4 ounces, pack them in your checked luggage. Additionally, if you’re traveling with a laptop computer, you have to take it out and have it screened separately when you’re going through security, but e-readers, smartphones, and tablets can stay in your carry-on bag. Finally you have to remove your shoes when going through security as well, unless you qualify for an exemption.
Those are just some of the regulations in place now. They change regularly, so that’s why it’s important to check them before every trip.
How do I watch movies on JetBlue flights?
JetBlue offers free Wi-Fi on all flights so you should have no problems keeping yourself occupied. They also offer seatback entertainment with Sirius XM radio and DirectTV. However, there are only three movies available on the seat back screen. You do have access to a bunch of content on your own device.
Even though you can’t bring beverages through the security check, you can bring food, which is a smart move. Travel agent Dahl told me, “Food is low on the priority list of airlines, especially if you’re in coach class, so don’t wait until you get to the airport to buy your snacks — save the money for your trip.” I highly recommend doing this as not only will you have what you know you like to eat, but also you’ll avoid airport and airplane food that can be super expensive. You might also find your options limited if you’re at a smaller airport, if your short on time, or if you’re flying during off-hours.
Obviously you shouldn’t bring something that needs to be heated as you’re not going to have access to a microwave. And avoid bringing food with strong odors out of consideration for your fellow passengers. But by all means, pack a sandwich, last night’s leftovers, some fruit, or some nuts to get you through the trip.
This is more of an issue for domestic travelers, as international flights still give you complimentary meals. Still, even if you don’t bring a full meal, having a snack when you want one is important.
How To Charge Your Phone Without An Outlet
You can bring a power bank or a battery charger on the plane in your carry-on baggage. That way if your particular airline doesn’t have any outlets you’ll have an alternative charging technique for your mobile devices.
Lithium-ion batteries are allowed through airport security if they are under 100-watt hours. You are not permitted to pack them in checked luggage.
For lithium-ion chargers, 100-watt hours is equivalent to 26,800 mAh (milliamp hours). So if your portable charger is under 26,800 mAh you are free to pack it in your carry-on.
Here’s is a good power bank that is under the maximum power capacity for carry-on luggage.
Buy it on Amazon!
The Anker PowerCore 26800 can charge most phones 6 times so you won’t need to worry about running out of power.
Even when planes have power outlets sometimes they don’t work, and power outlets in airports are often in high demand, so it’s better to be safe than sorry and bring your own power.
What happens if a plane flies too high?
As previously explained, the higher the altitude, the less dense and thinner the air is. Since lift is generated by the difference in air pressure, there comes a point where the air will be too thin for the aircraft to fly. Additionally, if the plane gets too high, there won’t be enough oxygen to power the engines.
There’s also a risk for passengers to develop hypoxia – this condition happens when there isn’t enough oxygen supply for the body to thrive on. If the cabin pressure suddenly malfunctions and drops, passengers will experience hypoxia – the most common symptoms are: euphoria, visual impairment, severe headaches, drowsiness, and impaired judgement. This is especially terrifying because when left untreated, hypoxia can potentially cause permanent brain damage – all in the span of seconds.
How do planes steer?
What is steering?
Steering anything—from a skateboard or a bicycle to a car or a jumbo jet—means you change the direction in which it’s traveling. In scientific terms, changing something’s direction of travel means you change its velocity, which is the speed it has in a particular direction. Even if it goes at the same speed, if you change the direction of travel, you change the velocity. Changing something’s velocity (including its direction of travel) means you accelerate it. Again, it doesn’t matter if the speed stays the same: a change in direction always means a change in velocity and an acceleration. Newton’s laws of motion tell us that you can only accelerate something (change its speed or direction of travel) by using a force—in other words, by pushing or pulling it somehow. To cut a long story short, if you want to steer something you need to apply a force to it.

Another way of looking at steering is to think of it as making something stop going in a straight line and start going in a circle. That means you have to give it what’s called a centripetal force. Things that are moving in a circle (or steering in a curve, which is part of a circle) always have something acting on them to give them centripetal force. If you’re driving a car round a bend, the centripetal force comes from friction between the four tires and the road. If you’re cycling around a curve at speed, some of your centripetal force comes from the tires and some comes from leaning into the bend. If you’re on a skateboard, you can tilt the deck and lean over so your weight helps to provide centripetal force. In each case, you steer in a circle because something provides the centripetal force that pulls your path away from a straight line and round into a curve.
Steering in theory
If you’re in a plane, you’re obviously not in contact with the ground, so where does the centripetal force come from to help you steer around a circle? Just like a cyclist leaning into a bend, a plane “leans” into a curve. Steering involves banking, where the plane tilts to one side and one wing dips lower than the other. The plane’s overall lift is tilted at an angle and, although most of the lift still acts upward, some now acts sideways. This sideways part of the lift provides the centripetal force that makes the plane go round in a circle. Since there’s less lift acting upward, there’s less to balance the plane’s weight. That’s why turning a plane in a circle will make it lose lift and altitude (height) unless the pilot does something else to compensate, such as using the elevators (the flight control surfaces at the back of the plane) to increase the angle of attack and therefore raise the lift again.
Artwork: When a plane banks, the lift generated by its wings tilts at an angle. Most of the lift still acts upward, but some tilts to one side, providing centripetal force that makes the plane steer round in a circle. The steeper the angle of the bank, the more the lift is tilted to the side, the less upward force there is to balance the weight, and the greater the loss of altitude (unless the pilot compensates).
Can you use wireless headphones on JetBlue?
Lucky you: As of January 2017, JetBlue became the first airline to provide free, high-speed Wi-Fi on all flights. The carrier’s signature “Fly-Fi” wireless internet provides coverage for passengers from departure to arrival gate — so you don’t have to wait until 10,000 feet to connect.
