A YouTube star known for pranks and hoaxing says he was removed from a Delta Air Lines flight after speaking Arabic.

In a series of tweets and videos, Adam Saleh described the incident on Delta Flight 1 from London Heathrow Airport to New York's John F. Kennedy Airport.

"We got kicked out of a @Delta airplane because I spoke Arabic to my mom on the phone and with my friend slim," Saleh wrote. In one tweet, he called for a boycott of Delta.

Delta said two customers were removed from the flight and later rebooked "after a disturbance in the cabin resulted in more than 20 customers expressing their discomfort."

Saleh later tweeted that he was "on another flight with a different airline heading to NYC after being checked for 30 minutes."

Delta said in a statement Wednesday evening: "Based on the information collected to date, it appears the customers who were removed sought to disrupt the cabin with provocative behavior, including shouting. This type of conduct is not welcome on any Delta flight.... what is paramount to Delta is the safety and comfort of our passengers and employees. It is clear these individuals sought to violate that priority."

Saleh's videos on YouTubes depict various pranks and "experiments."
