What is the maximum number of guide or assistance dogs allowed per aircraft?

The maximum number of guide or assistance dogs allowed per aircraft is indeed four. This limit is in place to ensure passenger safety and comfort, taking into account the aircraft's space and the need for effective management of the dogs during the flight.

Having a maximum of four assistance dogs means that operators can adequately accommodate passengers who require these animals, while also balancing the overall capacity and operational considerations of the flight. Each assistance dog typically needs to be properly trained and may occupy a designated area to ensure that there is minimal disruption during the journey. Thus, this guideline helps maintain a safe environment for all passengers, including those traveling with an assistance dog.
