Before you take faithful Rover or Tabby to sit with you on your next air journey, be sure to have all the required documents. They’re especially necessary if your companion is a medically-required or certified comfort animal.

Airline security is always on the look-out for people attempting to fly with animals in passenger seats. Recently, a passenger on Singapore Air tried to go aboard with four kittens hidden in his pants, but the meows gave him away. Often it could cost passengers with illegal pets fines and/or imprisonment. Importation of animals into Singapore without a license is illegal and carries a maximum penalty of a $10,000 fine, jail for up to a year, or both. Similar legal actions against offenders are in effect in other world airports.
