There's only one thing worse than some annoying kid kicking the back of your seat during a flight — and that's your seat taking flight!

Unfortunately, passengers aboard not one, but two different American Airlines flights had that dreaded experience of their seats coming loose mid-flight at the weekend.

The first incident took place on Saturday night on a flight from Boston to Miami, when seats suddenly came unbolted in mid-air.

The passengers were moved to other seats (thankfully they were stationary), but the plane was diverted and had to make an emergency landing at New York's JFK Airport.

Loose seats were again discovered on a second flight between New York flight and Miami, sparking concerns about the state of American Airlines' carriers.

While no-one was harmed in either incident, passengers were still shocked by the bizarre occurrence.

"The seats flipped backwards," one passenger, who chose to remain anonymous, told ABC News in the US. Watch the video above to hear her description of the crazy "legs-in-the-air" moment.

American Airlines has taken eight of its aircraft off the runways for inspection, and the Federal Aviation Administration is looking into both incidents.
