It was a real flight to nowhere.

Passengers aboard a recent international American Airlines flight were flabbergasted after the plane turned around five hours into the trip — without any explanation.

One of the flummoxed flyers detailed the aerial about-face in a viral Instagram video.

“American Airlines needs a lesson in effective communication,” Jimin Lee, 41, captioned the clip of the incident, which occurred Sept. 7 aboard an AA flight from Dallas, Texas, to Seoul, South Korea, the Daily Mail reported.

The Post reached out to both Lee and American Airlines for comment.

In the clip, captioned “new fear unlocked,” Lee included footage of a headrest screen that depicted the aircraft’s flight path as it traveled across the contiguous US and part of the Pacific Ocean before turning around and heading back to Texas.

Worst of all, crew members provided “zero explanation” for aborting the flight bound for Incheon International Airport, per the Insta-post.

“Just relax and enjoy the rest of our flight,” a flight attendant is heard saying over the intercom.

Lee wrote that her “soul had left” her at that point.

Lee claimed that crew later said that they’d diverted because the “right side of [the] bathrooms” weren’t working and seemingly joked that the pilots asked for a screwdriver to “fix” it.

The flustered flyer eventually sought solace in snacks she had onboard.

“The only vice I had available to me — Flaming hot [Cheetos],” Lee wrote along with footage of her chowing on the cheese-dusted chips while the flight headed home.

She added that she needed “a ramyun [Korean for instant noodles] and a strong drink.”

The ill-fated flight eventually landed back in the Lone Star State a whopping “nine hours” after takeoff, per Lee, who wrote she was “lost for words.”

Fortunately, it appears that the Texan eventually made it to Korea on another flight, according to followup clips showing her enjoying the sights and delicacies in the East Asian country.

Instagram users were appalled by Lee’s flight from hell, with one writing, “‘Just relax’ would have me reeeeling with anxiety.”

“I hope you didn’t have kids with you! Yikes, that is so scary!” said another.

A third declared: “I avoid AA at all costs.”

However, some armchair air travel experts suggested that the pilots were simply erring on the side of caution and didn’t want to create “mass panic” by announcing the nature of the problem.

While the exact issue remains unclear, air captains have diverted jets for a number of bizarre reasons, from an onslaught of inflight diarrhea to a laptop that was stuck in a seat and posed a fire hazard.
