New Delhi:Embarrassed Praful Patel on Tuesday dashed off a letter to Union Civil Aviation Minister Ajit Singh seeking a probe into the allegation that Air India had arranged a special aircraft to accommodate his family members on a trip to Maldives in 2010, when he was the Civil Aviation Minister.

In a letter to Singh, Heavy Industries Minister Patel referred to news reports appearing in the press relating to an Right to Information (RTI) query wherein it has been alleged that some members of his family travelled from Bangalore to Male and returned back in an Air India flight which was changed to a larger aircraft so as to enable them to travel by business class.

"I am personally embarrassed and pained about the impression that is sought to be created that the passengers travelled either on free tickets or were upgraded to business class and it was done at my behest, whereas they were actually fully paid business class passengers," the letter states.

"Air India or any private airline has never done any change of aircraft type ever before if they have more bookings or for commercial reasons," he said in his letter. Therefore, Patel requested Singh to immediately order an enquiry and ascertain all the facts or probe the matter.
