United said Tuesday that it will halt PetSafe reservations while it reviews the service, which lets customers ship pets as cargo. Fees can run several hundred dollars for a medium-size or big dog.
The review, expected to finish by May 1, doesn't affect pets in the cabin like the French bulldog that died last week after a flight attendant ordered a passenger to put her pet carrier in the overhead bin.
After that incident, United chartered a private jet to return the German shepherd from Japan. Two days later another flight made an unplanned landing in Ohio because it was carrying a dog that was put on the wrong plane.
