United Airlines flight is forced to DIVERT after a dog POOPED in first class aisle - as passenger shares horrifying images of the 'mess' that left travelers 'ill' and took TWO HOURS to clean up

Delayed flights are one of the most irritating parts of flying, but a fight being diverted due to a dog's defecation is much worse.

But that was the case on a recent United Airlines flight, which was forced to land half-way through its journey after a dog relieved himself in the aisle of the plane - right outside the first class bathroom, a spokesperson confirmed to DailyMail.com.

The messy incident was captured by Reddit user gig_wizard, who said they were on the five-hour Flight 422 from Houston to Seattle on Friday, April 7, when the incident occurred.

'Dog had messy accident in the aisle right in first class,' the passenger wrote alongside the photo.

The Reddit user said the flight was diverted to Dallas Fort Worth International Airport, where the ground crew spent over two hours trying to clean the carpet with paper towels, noting the smell made them ill.

'Gate agents kept yelling at passengers and the cabin crew,' they continued.

'The smell never quite went away.'

The multi-hour cleaning effect was ultimately unsuccessful, after the first class toilet declared unusable.

'The dog mess was apparently unresolved in there,' the passenger wrote. 'Food went bad while on the ground so very few snacks left.'

In an email to DailyMail.com, United Airlines confirmed that the incident had occurred but declined to share any other details.  

However comments on the post slammed people who bring their dogs on flights, some even sharing their own stories. 

'All animals need to either be in a crate or in the cargo hold. Only service animals should be for the blind. You don't need an "emotional support dog" for a freaking plane ride,' one user raged.

'Dog people are crazy and I am sick of the "he's my baby" mentality of owners. It's a freaking animal. And the owner should be made to clean that mess up. Take a dog on a plane-clean up your mess,' they concluded.

Another user agreed, sharing they moved to Germany recently and had to fly with their pet.

'I don’t want my dog in cargo, but that’s where most dogs belong,' they wrote. 'Too many people have main character energy and think their dog should be in cabin. If it’s a carrier fine, but so many aren’t. There are legit service dogs, but the rules have got way too lax.'

Another passenger shared a tale from their flight experience with a canine companion. 

'The first time I flew with my dog he escaped his bag while I was sleeping and took a crap in the aisle. I felt sooo bad and I was lucky it was solid,' they reminisced.

'Since then I’ve learned to travel way better with him and he is now better trained to stay in his bag under the seat for the whole flight. Now you don’t even realize he’s there,' they shared. 

In January, passengers were horrified after a fellow traveler pooped their pants on their flight - and left the feces 'spread out like peanut butter' all over the seat.

One of the disgusted travelers took to Reddit to share their dismay over the situation - and it quickly went viral, while sparking some suggestions that it may have been a fabricated story.
