The details are very sketchy but it seems tha Mo'Nique was thrown off an United Airlines flight while on her way to NY to guest star on 'The View'. It seems a bit fishy because I doubt flight attendants would throw passengers off the airline without justifiable cause... but that is what Mo'Nique is saying happened to her. I think that she is leaving a few key pointers out of the story. When United Airlines gets around to making an offical statement we will learn more.

Comedienne MO'NIQUE says she's considering legal action against United Airlines after reportedly being asked to leave a flight, "ET" has confirmed. The star of the big screen's 'Phat Girlz' and host to small screen "Mo'nique's Fat Chance" (a television beauty pageant for large women) had reportedly boarded a flight to New York in first class when, she alleges, flight attendants threw her off the plane without giving her a reason why, referring to her as a "threat."
Mo'nique tells "ET" exclusively, "It was incredibly humiliating and embarrassing for me. Police were everywhere." The actress was attempting to fly to New York in order to guest host "The View." She did make that engagement, sitting down with the ladies this morning.
United Airlines had not responded to the allegations at press time. (source)
