I’m as sensitive, if not more so, to the sight and smell of poop and barf. But on a plane, I get it together, like when a daughter barfed beside me upon landing: went into the barf bag, and I casually strolled out and deposited the gift in the garbage.

Flight 598 was already two hours late when it took off from Los Angeles International Airport.

Things went downhill from there.

A terrible smell spread through the cabin. And it got worse.

The source? A service dog, belonging to a passenger, heeded nature’s call smack in the center aisle. And then the mutt pooped again.

Then the passengers started vomiting.

Disgusted passengers took to Twitter Wednesday to voice their displeasure. Especially after the pilot announced they would be making an emergency landing in Kansas City, Mo., because the plane had run out of paper towels and the mess was clogging the aisle.

“The second time after the dog pooped they ran out of paper towels, they didn’t have anything else,” passenger Steve McCall told “Inside Edition.”

“The pilot comes on the radio, ‘Hey, we have a situation in the back, we’re going to have to emergency land!'” McCall recalled.

Micaela Connery tweeted “after being delayed 2 hours we get grounded because of dog poop on the plane. A 7 hour trip is now pushing 14.”
