United Airlines said the giant rabbit that died traveling from London to Chicago didn’t meet its maker while the plane was in the air.

Spokesman Charles Hobart told the Guardian that the 10-month-old, 3-foot-long rabbit, named Simon, was alive when it was taken off the flight at O’Hare Airport after landing Tuesday.

The animal — about to be crowned the world’s largest bunny — appeared healthy and showed no signs of distress and was placed in a pet facility run by the airline about 30 minutes later, Hobart continued.

But shortly after, the rabbit was found dead when an employee opened its cage.

The airline has said it is probing how the Continental Giant rabbit suddenly croaked — even though its owner said the large lagomorph was “fit as a fiddle.”

“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,” said Hobart.

Meanwhile, United CEO Oscar Munoz equated lost luggage with a dead pet during a ham-handed apology Thursday for the airline’s latest gaffe.

Munoz lumped the two unrelated circumstances together in an interview with Lester Holt set to air in full on NBC’s “Nightly News.”

“We are deeply sorry for the loss of anything from your luggage to, of course, a loved pet,” Munoz said.
