Vastavam web : An Indian-origin man in the US has claimed that the United Airlines cancelled his flight reservation because he filmed an employee during an altercation, the latest public relations headache for the under fire airline. Navang Oza, 37, said he was refused entry on a flight to the West Coast after he started recording his experience on his mobile phone. Oza was quoted by KNTV as saying that he was checking in Monday for a flight home to San Francisco from New Orleans when he complained to a United Airlines agent about a USD 300 charge for his luggage. Oza said he paid USD 125 to check the same bag on the first leg of his trip. Unable to get an explanation, Oza said he decided to do what many other frustrated passengers have done and film the dispute. Oza posted an unedited clip of the lengthy interaction with the ticket counter worker in New Orleans.
