Commercial flights aren’t known for their comfort — especially if you're flying in economy class.
And if you're on a long-haul flight (six to 12 hours) or an ultra long-haul flight (greater than 12 hours), comfort is even more important.
While you can't do anything about those shrinking airplane seats, there are several tips and tricks that can make those lengthy flights more bearable.
Choose your seat wisely
He also says sitting as far forward as possible can reduce noise, and avoiding the rows surrounding bulkhead seats can be beneficial since families with children are often seated there.
Generally, aisle seats are your best bet for comfort because they allow more room for stretching and give you easier access to the aisle and bathroom.
If you're on an airplane with a three-row configuration, the best seats are the aisles of the middle row because they give the people in the middle two options to reach the aisle.
While window seats can have great views, they've been linked to deep vein thrombosis because people in these seats are often less likely to get up and move around because they don't want to disturb their seatmates.
While checked-baggage fees might encourage you to bring more stuff on the plane, keep in mind this often means less legroom.
To ensure you have as much space as possible, put your carry-on bag in the overhead compartment and tuck a few items you'll use during the flight — books, headphones, etc. — into the seat-pocket.
Be sure to pack an in-flight toiletry case with basic items like a toothbrush, hand sanitizer, medicine and anything else that will make your flight more comfortable.
Other items not to forget: ear plugs, an eye mask, a neck pillow and noise-cancelling headphones.
Also, bring books, movies, music and anything else that will help you pass those long hours in the air. While most planes provide seat-back entertainment, older planes may not. Plus, you're limited to watching whatever movies and TV shows the airline provides. Several entertainment streaming services like Netflix and Amazon Prime allow subscribers to download movies and shows to their mobile devices so users can watch the programs without Wi-Fi. It's best to download at home or somewhere with a strong internet connection and not rely on an airport's Wi-Fi.
It may seem like a no-brainer, but make sure to bring chargers for all your devices. Most planes provide outlets; but to be on the safe side, you should also bring a rechargeable battery that can charge while you're on the go.
Finally, dress comfortably and be sure to layer.
Plane cabins are dry environments, so it's important to stay hydrated. Skip the alcohol and caffeinated beverages, and drink plenty of water, even if you don't feel thirsty.
Keep in mind that airline food is high in sodium because it's more difficult to taste most foods at 30,000 feet, and all that salt can further dehydrate you.
While you might have heard that breathing planes' recycled air can expose you to bugs, you're actually more likely to get sick from touching your armrests, seatbelt, tray table or in-flight magazine.
A team of microbiologists from Auburn University led by James Barbaree conducted an experiment in 2014 where they sanitized several parts of an airplane where the spread of germs may take place: tray table, toilet button, armrest and seat pocket. Then, they applied the antibiotic-resistant superbug MRSA and E.coli. Their test results showed that MRSA lived for at least a week and E. coli lasted four days on the surfaces.
So it's a good idea to wipe down these surfaces with sanitizing wipes.
You're going to be sitting for hours on end, so be sure to stretch often and get up from your seat and walk a bit to improve circulation.
To avoid "airplane ear" after you land, chew gum right before and during landing. The chewing helps produce saliva, which forces you to swallow while chewing. The swallowing motion relaxes your Eustachian tubes, which connect your nasopharynx (the way upper part of your throat, behind the nose) to the middle part of the ear. The tube equalizes air pressure on either side of your ear.
If you still experience pain from the pressure in your ear after you've landed, try the Valsalva maneuver. Close your mouth and pinch your nostrils shut. Then, slowly pretend you're like blowing your nose. The motion will force your tubes to open.
When to sleep
To get a good idea of when you should be sleeping, change the time settings on your phone or computer to that of your destination. Also, pay attention to the cabin crew, who often give visual clues by dimming the lights.
It can be tempting to pass the hours by sleeping, but keep in mind that getting too much shut-eye can throw off your internal clock.
If you plan to take a sleeping aid, test it beforehand. You don't want to have an adverse reaction while you're in the air.
Finally, listen to your body. If your eyelids start dropping, take a nap — but don't stress if you can't fall asleep.
How to sleep
Obviously, a seat in first class that allows you to lie back further will help you sleep better. But what if you're flying economy? Aircraft seating and interiors designer Adam White, director of Factorydesign, gave Travel + Leisure some tips on sleeping as comfortably as possible no matter where you're sitting.
“First get comfortable temperature-wise. That may mean standing up with your blanket and wrapping it around you and then put on your seat belt so that the crew can see that you’re strapped in,” he said. “That way the flight crew won’t find a need to wake you if the seatbelt light goes on.”
He also recommends wearing noise-canceling headphones and adjusting the light when possible to improve conditions for sleeping.
The best time to use the bathroom
To ensure a clean restroom and minimal wait time, Lifehacker suggests using the bathroom just after flight attendants have served food and moved out of the aisle.
While it can be cumbersome to move your tray table and maneuver yourself around other dining passengers, this is the ideal time because passengers are occupied with their food.
Just after flight attendants collect meal trays is often the busiest time for airplane bathrooms.
