With spring travel season here and summer right behind it, there are some very smart ways to make air travel a little more pleasant for everybody involved.

It means following some basic rules of good etiquette — etiquette that a lot of people, judging by dramatic experiences shared in a wide variety of platforms, appear to have left behind.

Jacqueline Whitmore, founder of Protocol School of Etiquette in Palm Beach, Florida, and a longtime etiquette expert, shared some basic rules of thumb when traveling by air.

FLIGHT PASSENGER'S ‘MANSPREADING’ BEHAVIOR GETS LITTLE SYMPATHY FROM OTHERS: ‘DOESN’T GIVE YOU THE RIGHT'

"With the seats getting smaller and smaller these days, we all have to learn to get along," she said of air travel.

Here are 20 top tips for more pleasant and civil travel — with a few cheeky reminders from Whitmore, too, for passengers who just can't help engaging in problematic behaviors on board an aircraft.

1. If you bring food on board — "and if you’re smart, you will," said Whitmore — "don’t bring anything with a highly identifiable or offensive smell," she added.

"There’s nothing more annoying than having to smell someone’s greasy fish tacos."

2. If you can’t lift your own bag, stow it instead of carrying it on. "Don’t rely on others to risk pulling a muscle and lifting it for you," she also said.

3. Wipe down the sink in the lavatory and leave it in better condition than you found it. "Don’t treat it like your own bathroom," said Whitmore.

4. If you have to swap seats with someone, make sure the new seat is comparable with the one you’ve been assigned.

Said Whitmore on this point, "Don’t assume you’re entitled to an upgrade just because you paid for a cheap seat and you want to sit with a family member in a more expensive seat."

5. Every passenger has the right to recline his or her seat, said Whitmore. "That’s what the seats were designed to do," she said.

She advises, however, that people "keep their seat upright during take-off, landing and during meals," as is usually advised by aircraft personnel.

"If you feel compelled to recline all the way for maximum comfort, take a quick peek to avoid breaking someone’s knees or laptop," she added.

6. If your seatmate is wearing headphones or typing on his or her computer, this clearly means, "Do not disturb," said Whitmore.

"If someone chooses to engage in a conversation with you, keep your voices down. No one wants to hear your conversation," she said.

7. An airplane is no place to practice your agility skills, noted Whitmore.

"If you’re seated in a window or middle seat and must go to the lavatory, gently tap your seatmates and say, ‘Excuse me,’ instead of crawling over them."

If you’re on a long-haul flight, she suggested people do their business "after you finish your meal, even if you don’t think you have to go." This will eliminate the need to disturb others when everyone is sound asleep.

8. "Keep your dirty feet off the seat in front of you. This is not only gross, it’s unsanitary," said Whitmore.

She also said, "Don’t treat the airplane like your living room. If you must air out your feet, keep your socks on or wear slippers. What may look like water on the floor in the lavatory is something else instead."

9. "Keep your arms and legs to yourself. The seats may be getting smaller by the day, but that doesn’t give you the right to spill over into someone else’s space or put your head on another person’s shoulder — unless, of course, you know that person well."

10. Never put your belongings in someone else’s overhead bin or underneath someone else's seat, said Whitmore.

11. If you’re in an aisle seat, keep your long legs and sharp elbows out of the aisle.

Added Whitmore on this point about minding one's space, "And don’t even think about putting your food, drinks or trash on someone else’s tray table without their permission."

12. Control your children. "Nothing is cute or amusing about getting the back of your seat kicked, your hair pulled or watching someone else’s children running like wild banshees up and down the aisle," said Whitmore.

To this end, she said it's wise for parents or guardians to "bring plenty of games, toys and snacks to amuse your child. Crying babies are an exception as they may have aching ears. The crying helps alleviate the pressure. So does a bottle of milk, water, juice or Benadryl."

13. The unlucky person in the middle seat gets one perk: sole ownership of the armrests, according to Whitmore.

She added, "The person in the window seat gets the best view. The person in the aisle seat gets more breathing space as well as the benefit of getting out of the plane quicker in the event of an emergency."

14. Avoid grabbing the back of someone’s seat when you sit down, get up or walk down the aisle. 

Said Whitmore, "The headrests are not there to help you balance yourself as you get in your steps or make the long trek to the lavatory."

15. Be respectful to the flight attendants. "Their job is hard enough and they don’t make enough money to put up with your b.s.," said Whitmore.

She added, "They’re there for your safety, not to wait on you hand and foot. Furthermore, if you’re kind and considerate, you might possibly get an upgrade or an extra alcoholic beverage."

16. "Unless you like to be detained by the TSA, keep your voice down, follow the rules and treat the flight attendants with respect," she also said.

17. Also, "if another passenger is ticking you off, don’t take matters into your own hands. Ask a flight attendant to step in and be the bad guy."

18. When the plane hits the tarmac, "don’t race for the door," said Whitmore. Instead, "wait for the seatbelt sign to turn off before getting up. Be patient, wait your turn and file out in the order in which you are seated."

19. On this related point, "if you have a connecting flight to catch, ask politely before skipping the line."

20. Wear headphones. "They come in handy whenever you want to cancel out a crying baby or avoid getting into a conversation with someone," said Whitmore.

She said they also should be worn whenever you watch a movie on your phone, tablet or computer.

"This may be common sense," she also noted — "but most people forget to pack their common sense (and their manners) whenever they travel."

A judge presiding over Donald Trump’s arraignment in a Manhattan courthouse Tuesday afternoon has denied a request from several media outlets to allow cameras to cover live courtroom proceedings, according to court documents.

New York Supreme Court Judge Juan Merchan said the court would allow a "limited number" of videographers, photographers, and radio journalists to be present but denied the motion to allow photos or live video during the court session.

In his ruling, Judge Merchan said he considered "all relevant factors" — which included whether the camera coverage would "interfere with the fair administration of justice… with law enforcement activity, the objections of the Defendant; and limitations related to the physical structure of the courtroom" — but ultimately denied the motion.

He ruled integrity of the court’s impartiality outweighed the "monumental significance" of the case and the "unparalleled public interest" it has generated.

TRUMP CONFIRMS HE WILL APPEAR IN COURT IN NEW YORK CITY ON TUESDAY FOLLOWING HIS INDICTMENT

Merchan went on to affirm that members of the media will be allowed to enter the courtroom, but electronic items like cell phones would not be permitted.

"The use of cell phones, laptops or any electronic devices will be strictly prohibited in the courtrooms. Any such devices will have to be turned off and secured outside of public view while in the courtrooms," he wrote.

In the ruling, Merchan said cameras could be used in the hallway of the building. He also approved the use of two overflow rooms for additional seating, which was another request from media members.

Trump landed in New York on Monday. His arraignment is scheduled for 2:15 p.m. Tuesday.

In his reasoning, Judge Merchan said Trump's arraignment has "unparalleled public interest and media attention" and "that this indictment involves a matter of monumental significance [that] cannot possibly be disputed."

"Never in the history of the United States has a sitting or past president been indicted on criminal charges," he added.

MOST AMERICANS SUPPORT TRUMP INDICTMENT, BUT THINK POLITICS PLAYED A ROLE IN BRAGG'S DECISION: POLL

"The populace rightly hungers for the most accurate and current information available," Merchan continued. "To suggest otherwise would be disingenuous."

"Understandably, the News Organizations want to fulfill their responsibilities and argue that obtaining the broadest possible public access helps advance that mission. Unfortunately, although genuine and undoubtedly important, the interests of the News Organizations must be weighed against competing interests. This Court is now called upon to engage in that balancing exercise."

In the request, District Attorney Alvin Bragg, on behalf of the people of New York, argued the presence of cameras in the courtroom "raises a number of concerns."

Among those concerns included "the prejudicial impact of pretrial publicity on the jurors, the impact on the truthfulness of the witnesses, responsibilities placed on the trial judge to assure a fair trial and the impact on the [defendant]," court documents show.

Merchan was first appointed to the New York State Court of Claims by Democratic Gov. David Paterson in 2009. He then began serving as an acting justice on the New York Supreme Court that same year.

Trump is on trial for monetary payments made to two women during his successful 2016 presidential campaign. He has been charged with 34 felonies related to the payments.

A potential guilty verdict in the case would not prevent Trump from running for the White House in 2024.
