An air traveler took to social media sharing a video of a large dog in a row, sparking a discussion on Reddit.

Titled the “Bull mastiff in Comfort+,” the user captioned the post, “This is getting ridiculous.”

On the sub-Reddit forum titled “r/delta,” users debated whether a dog of that size should be able to board a flight.

“Should be illegal. No one is comfortable,” commented one user.

Another said, “Bull Mastiff in Comfort + making everyone else Uncomfortable +. (That poor dog doesn’t even look comfortable.).”

“Is this real?! I don’t believe this?! There is no way,” questioned another.

Many users expressed their affection for pets, but said this was too far.

“I love dogs and have my own, but this looks miserable for the pup… If you have a dog this size, then pay for an additional seat so everyone can be more comfortable. I wouldn’t even try to do this with my 45lb dog,” a user commented.

Another person added, “I love my big dogs just as much as the next person, but this has been on the rise the last few years and something definitely needs to change.”

“I’m so confused.. my pup had to fit in a bag of certain dimensions AND under the seat in front of me. How on earth was this allowed,” one Reddit user questioned after a person posted a video showing a large dog (not pictured) traveling on a flight. (iStock)

“As much as he looks like a sweet boy I would one hundred percent bring this up to Delta and as for some sort of compensation (while you still can),” suggested one user.

A Redditor added, “This is insane. Look, dogs are nice. They do NOT belong everywhere. Especially in cramped, confined seating on a metal tube thousands of meters up.”

Some users noted that the pet could have been a “service” dog.

“If you have that notation….you get to bring your Service Dog on the plane. If large service dog, you have to purchase a 2nd seat,” posted a user.

“This would only happen if the owner claimed the dog to be a service animal,” one person wrote.

“I’m so confused.. my pup had to fit in a bag of certain dimensions AND under the seat in front of me. How on earth was this allowed,” one user questioned.

When a commenter asked if the passenger did anything to address the situation, the passenger replied, “What can you do? The owner of course apologized and behaved well. But cmon. A 100 lb dog?! It was a full flight so couldn’t move”

On Delta’s website, the airline lists guidelines for traveling with pets. 

“Small dogs, cats and household birds can travel in the cabin for a one-way fee that is collected at check-in,” says the site.

It adds, “The pet must be able to fit in a soft-sided ventilated pet kennel that will go underneath the seat directly in front of you.”

The kennel size recommends maximum dimensions of 18″ x 11″ x 11″ to fit most aircraft types, but varies on plane size.
