For some airline passengers, flying can be a daunting and stressful journey. For others, it's a welcome experience to see the world from hundreds of metres in the air.

Looking for advice on what to do (and not to do) during a trip? CTVNews.ca spoke with flight attendants about their best travel tips.

Flight attendant Sean Price

Don't go barefoot

Sean Price, a part-time flight attendant, says many people like to remove their shoes and socks once they're in the airplane, including while in the washroom.

"Generally speaking, any substances you come in contact with in that lavatory are probably undesirable, and we tend to see those same feet reappear in the cabin sometimes on arm rests, sometimes on table trays," Price, who has been a flight attendant for a major airline in Canada for 19 years, said in a video interview with CTVNews.ca. Price is also the academic program manager for the Flight Services program at Seneca Polytechnic in Toronto.

"So we would not recommend wearing bare feet in the lavatory specifically because there's lots of opportunity for cross contamination there."

Flight attendants will generally tidy up the washroom during a flight, but they don't fully clean it until the aircraft lands, he noted. For long-haul flights, planes are deep-cleaned at the destination.

"You can imagine flights to maybe Vancouver to Sydney can take 16 hours," Price said. "There's lots of opportunity for substances to build up in that lavatory and then on your foot."

On short-haul flights, cleanups are generally quick, he added.

Don't change babies at your seat

Another common practice to avoid is changing babies' diapers on the surface of seats.

Instead, use the washroom and use the bags to dispose of soiled material.

"We have lots of baby change tables on the aircraft," Price said. "We can assist you in any way possible. ... but we would prefer that you go to the lavatory where there is a change table that's safer for (the) baby and cleaner for anyone else who's using that seat."

Don't use devices without headphones

Many people use their personal devices on flights to watch movies and shows and entertain themselves. The problem is when they don't use headphones.

"You can imagine that on a red-eye flight when ... you're trying to gain some sleep," he said. "If you've got 30 people watching a TV show at full volume in the cabin, it can get quite chaotic (and) disruptive."

Passengers should always use a headset or headphones, even if they're just receiving text messages or notifications, he said.

"Those consistent notification tones can be really, really distracting in the cabin."

Don't leave trash behind

If you have garbage, flight attendants would appreciate it if you give it to them during the flight, rather than stashing it somewhere.

"We do see a lot, after the flights deplaned, a lot of rows or seats that are pretty heavy with garbage or trash or other items," Price said.

Flight attendants check for any refuse throughout the flight and do a quick cleanup after passengers exit to ensure there are no delays for the next flight.

"We try to make sure that the aircraft is as clean as possible before landing because not only flight attendants but airline personnel are under immense pressure to turn that aircraft around super quickly when it gets to destination," Price said.

The amount of time airplanes are on the ground is very short, he pointed out. "Which means the cleaner the aircraft is, the quicker we can clean it on the ground, the quicker we can get you off to the next destination."

Don't be impatient

Price reminds passengers that airplanes have limits. "We're in a metal tube in the sky flying at enormous speeds around the world and that environment gives us quite a bit of limitation," Price said.

Some aircraft may not have an entertainment system, or passengers may not be able to buy food during the flight, for instance.

"Sometimes even turbulence may prevent us from doing a full service," Price said. "And in these circumstances, really, we're just looking for patience because flight attendants are doing the best they can in the environments in which they work and with the limitations that they have."

Don't be unprepared

Passengers may not be able to buy food during the flight. With this limitation in mind, Price recommends travellers bring non-liquid snacks and an empty water bottle. Water bottles full of water aren't permitted, but most airports have refillable water systems, he notes.

"So make sure you fill up that water bottle on the plane just in case if turbulence is so severe that we're not able to come out and give you a beverage," Price said. "If you bring snacks on board, it's just better preparing you so that if we aren't able to come around or maybe the airline doesn't offer the service you were expecting or maybe the flight isn't long enough to offer you a snack, at least you've got some backup in your bag."

Flight attendants

Consider checking carry-on bags

Consider the advantage of checked bags, said another flight attendant who spoke to CTVNews.ca.

"Carry-on luggage can save time, but checked bags can be more convenient for longer trips," said Ísold Wilberg Antonsdóttir, a flight attendant with low-cost Icelandic airline PLAY, in an email to CTVNews.ca. Antonsdóttir is based in Reykjavík, Iceland.

Although baggage fees are high, Price said in some cases, passengers can check in their bags for free at the gate or during boarding, should the airline run out of overhead bin space.

Check in your bag if you are offered the chance because smaller aircraft may have smaller bins for carry-on luggage, Price added.

"So bringing on a carry-on bag does seem to be the more economical solution. That being said, just remember that different aircraft are different sizes and this isn't a one-size-fits-all scenario," he explained.

Passengers on long-haul flights may find their carry-on bags fit in the overhead bin, but once they're on connecting aircraft, the bags may be too big.

"There tends to be a little bit of tension in the cabin when this happens," Price said. "If it doesn't fit in the bin, trust your flight attendant. They know what fits and they know what doesn't. And they are masters at Tetris. I'm telling you, they will know how to get the bag in. If they can't, listen to them and they will give you options, like checking your bag."

He also recommends using a smaller carry-on bag if you don't want to risk it not fitting.

"You choosing the largest carry on you can find often is more of a headache than it's worth," he said. "A smaller carry-on that's able to fit in more bins is going to be far better for you than a larger carry on that might not fit.”

Don't pay for baggage last minute

Price says it's more expensive to book a checked bag at the airport than purchasing it earlier.

"If you're gonna do a checked bag, oftentimes booking your ticket and booking the checked bag at the same time is cheaper," he said.

Purchasing tickets earlier is cheaper as well, he adds.

Don't forget your sweater

Cabin temperatures may not suit various people, so it's better to dress in layers, Price said.

Not all airlines offer blankets, he adds.

Emergency scenarios could happen even if you're travelling to warmer destinations.

"If we were to land in Toronto and we had an emergency and we had to evacuate the aircraft, you're going to evacuate the aircraft wearing flip flops and shorts and a tank top and it's negative 25 in Toronto," he said.

Like legroom? Avoid certain seats

Seats near the emergency exit have lots of legroom but usually don't recline, Price said.

"Remember that oftentimes an emergency exit seat won't recline because we can't have a seat that reclines into an emergency exit because it could prevent someone from evacuating," he explained.

Those sitting in emergency exit seats are also required to open the exit and help others if there's an emergency.

The areas near the washroom and galleys tend to be high-traffic areas, he noted.

He recommends people check out travel blogs if they want tips on which seats won't recline, or if they're looking for extra legroom.

Don't remove your seatbelt unless necessary

With the rise of incidents with turbulence, it's safer to keep your seatbelt on at all times, unless you're going to the washroom, Price said.

"Our pilots are really, really good at planning routes that avoid turbulence, but sometimes there's turbulence that's unexpected," he said. "Always wear your seatbelt, you can loosen it up ....

"Limit the time that you're walking around the cabin when you don't have a seatbelt because it isn't safe."

Don't be shy about asking for help

Flight attendants say if there's something you need or you have concerns, bring it up.

"A flight attendant would never ignore a passenger in need of assistance," Antonsdóttir said.

If you're worried about flying, tell a flight attendant, Price adds.

"Let us know. There are lots of things that we can do for you," Price said, noting passengers sometimes need hot tea, water or even the chance to meet the pilot to calm their nerves.

Another effective way to help jittery flyers is to talk it out, he said.

"We can walk you through it," Price said. "If you are nervous about a specific part of flight, (for example) takeoff and landing, we can be more attentive to you during those times that you're nervous."
