Flight attendant demands passenger spit out Zyn, leaving travelers confused about policies

Smoking and vaping are banned on flights, but it appears that smokeless nicotine pouches are allowed - depending on the airline. 

Pouches are allowed in both carry-on bags and checked bags, according to the TSA.

Recently, one flight passenger called out an airline in the "r/delta" forum on Reddit for an experience with chewing Zyn on board. 

"Delta flight, first class (not that that matters). They brought a cup out and asked me to spit my Zyn out."

The user added, "They said it was because it was a tobacco product. I didn't put up a fight and complied right away."

Redditors took to the comments section to share thoughts about the incident - and their own similar experiences. 

"Probably because the way you had it in your lip, it looked like a dip," said one user.

Another Redditor argued, "Zyn isn't tobacco. You can have it in flight."

"Tobacco or not, does it cause you to spit into a bottle or cup that could spill or be left stuffed in the seat pocket that someone else has to clean up?" said one person. 

"Then I'd say it doesn't matter what you call it," the person added.

A user commented, "It [is] allowed but be discrete. I see many people using them on flights, myself included, and as long as you're not doing it right in front of an FA, you're fine," the person added. 

One user claimed, "I was on a United flight a few days ago and the shopping/menu magazine in the seatback actually had a Zyn ad in it. It said something like, 'Flight ready.'"

"How would the FA even know what it is? Just looks like gum/mints," said another individual.

On Delta's "Contract of Carriage" section on its website, the airline specifies a no-smoking policy.

A Delta spokesperson said the policy also prohibits smokeless tobacco, including pouches and gum.
