A carrier with IATA/TSA/FAA compliance means it has a design suitable for short and long-haul flights. Whether it is a three-hour domestic flight or a 12-hour transcontinental journey, the airline crew should be able to monitor and care for their canine passengers throughout the trip. Such a carrier has the required features imposed by the organizations, as mentioned earlier. These features include a sturdy and leakproof bottom, multiple ventilation panels, and locking mechanisms, among others.
