A spokesman for United Airlines says the airline is reviewing its handling of a giant rabbit that died following a flight from London to Chicago.

The animal was alive and showed no signs of distress upon landing but died at a pet holding facility at the airport, spokesman Charles Hobart said.

"We won't know the cause of death because we offered to perform a necropsy free of charge — that's standard procedure — but the customer didn't want us to perform a necropsy, and we understand," he said.

Hobart said the airline offered compensation to the breeder but would not disclose the amount.

Breeder Annette Edwards told The Associated Press by phone Wednesday that a veterinarian checked Simon, a 10-month-old, 3-foot-long continental rabbit, shortly before the flight to O'Hare, from where it was set to continue on to Kansas City.

"Simon had his vet check just before getting on the plane," she said. "He was fit as a fiddle."

Simon had been purchased by a celebrity whom Edwards did not identify.

Bryan Bergdale of West Des Moines had purchased the rabbit for his boss to show at the Iowa State Fair.

Bergdale had driven last Thursday to Kansas City to pick up Simon when he received a call from United Airlines. Bergdale says "we'd built a pen and had toys all ready."

Bergdale, who manages farmland investments, says the rabbit cost his boss 415 pounds ($530) and shipping was 1,400 pounds ($1,800). He says he had a 5-foot-by-8-foot pen built in a farm garage in Norwalk and had planned for air conditioning to be piped in.

Bergdale said the United Airlines representative who called was "very nice" but didn't say anything about compensating him. He says "we're not quite sure what we're going to do."

United Airlines has been dealing with public relations issues after a passenger who would not give up his seat was dragged forcibly from a plane in Chicago three weeks ago.
