Photos of the clean-up operation show piles of paper towels trying to soak up the puppy poop.
“Ground crew spent [almost] 2 hours cleaning carpets with paper towels. Smell made me ill,” wrote the passenger.
After an hour and a half on the tarmac at Dallas Fort Worth, the flight was cleared to continue the 4-hour journey, in the same aircraft.
However the front toilet in the Polaris business class cabin was rendered unusable by the incident and there was no catering available for the flight.
“The smell never quite went away,” a passenger said.
The incident caused some to question the pet policies of the airline, allowing a dog loose in the cabin. However, it appears the animal was a service animal.
United doesn’t allow pets in the cabin on domestic flights, unless they are in a carrier that fits under a seat. Only service animals are allowed without a pet carrier.
The airline’s website recommends passengers with animals travel with plastic bags in case of such poo emergencies, as well as pet toys to keep them calm.
Last year Singapore Airlines refunded the fares of a Kiwi couple who were forced to sit next to a ‘farting’ lap dog, on a full flight to Changi from Paris.
