United Airlines continues to have problems with its bathrooms.

On Sunday, a United Airlines flight from Denver to Hawaii was diverted to San Francisco when the aircraft lavatories reached their capacity before the flight was scheduled to land in Kauai.

According to FOX 31, passengers Rich and Kristin Anderson said they were already flying over the Pacific Ocean when the pilot announced that the plane would be forced to land in SFO since the toilets hadn’t been serviced in Denver.

“I am very sorry that our lavatories had reached capacity while Flight 1219 was en route to Lihue,” said a representative for United in a statement to passengers. “A decision was made to turn back and land in San Francisco where arrangements were made to change planes. I can appreciate that this experience was disappointing and unpleasant.”

Flight 1219 departed Denver at 11:40 a.m. on Sunday and was supposed to be a direct flight to Kauai with a total travel time of eight hours, but due to the unexpected landing at SFO and plane switch, the total travel time jumped to more than 16 hours.

After the mishap, United Airlines apologized to their customers and offered 10,000 bonus miles or a $200 voucher towards future flights.

It’s certainly not the first time United Airlines has diverted a flight due to lavatory issues.
