United Airlines said it's suspending a program that transports pets in cargo holds.
It will stop accepting new reservations for its PetSafe program, though it will honor any reservations made through March 20, the airline said .
Passengers can still carry small pets with them in carry-on luggage.
The suspension comes as United reviews its pet transport policies, a process that should be completed by May 1, United said.
United has experienced some major pet-traveling disasters recently. Last week, a small dog died after it was put in the overhead bin on a United flight. Then the carrier mistakenly shipped a Kansas-bound dog to Japan, and in a separate incident, it had to divert another flight to Akron, Ohio, after the airline realized a pet had been loaded onto the flight in error .
