Social media star Boo the Pomeranian dog has died at the age of 12. His owners say he had shown signs of heart problems ever since his "best friend" - a dog called Buddy - died in 2017.
Fortunately, going into the flight, it seemed like new dog mom @yuenabei knew that her Pomeranian puppy, whose she has named Mung Bean, was going to be a total hit among her fellow passengers.
