Former Playboy model Annette Edwards, is understood to have accepted the sum after her rabbit, Simon, died at Chicago O’Hare airport, en route from London to a new home in Kansas, The Times reports.
A source told The Sun: “There was some sort of mistake and he was locked inside a freezer overnight.”
United has not confirmed the size of the payout.
The airline said: “We were saddened by the loss of Simon and have worked with Annette Edwards to reach a satisfactory resolution.”
Edwards, 65, has bred two of the world’s largest rabbits, including Darius, (4ft 4in), the record-holder and father of Simon.
