It seems that United Airlines is never short on controversies. The "passenger dragging" issue is still blowing up on social media, but yet another issue is being faced by United. This time, a bride and groom who they were kicked off their flight.

Michael Hohl and Amber Maxwell were flying from Houston to Liberia, Costa Rica, on a connecting flight. They had a layover at George Bush International Airport, and when they boarded their plane, they found a man sleeping in their designated seats, according to NBC News. Rather than waking the man, they decided to sit in Row 21, since they saw that nobody's sitting on them.

The couple said they did not think it was a big deal since their flight was only half-full and had a couple of empty rows. But when Michael and Amber sat in their seats, a flight attendant asked them if they are sitting in their designated seats, and when they told her no, she asked them to return to their ticketed seats.

Michael and Amber did not know that Row 21 are composed of "economy plus" seats, and when they asked for an upgrade, the flight attendant didn't agree. They immediately proceeded to go back to their ticketed seats but a US Marshal boarded the flight and told the couple to get off.

According to Fox News, the couple was afraid they are going to be treated the same way as the passenger involved in the United Airlines scandal, so they immediately got off the flight. "They said that we were being disorderly and a hazard to the rest of the flight, to the safety of the other customers," Michael said. "I think customer service and the airlines has gone real downhill. The way United Airlines handled this was really absurd."

But according to United, the couple's story is not true as there were no federal marshals involved in the incident. The couple was asked to deplane because they wouldn't follow the crew's instructions and kept on sitting the upgraded seats they did not purchase.

As a compensation, United Airlines rebooked the couple the following day, but according to Michael and Amber, it's likely they wouldn't choose to fly with United ever again.
