The less time your puppy spends cooped up, the better. Book “off peak” flights to avoid delays, and plan as few transfers as possible. Also aim to book your flight well in advance, as most airlines can accommodate only a limited number of pets.
Once you take to the skies, your puppy will either fly in the cabin with you or as checked baggage. How he travels will depend on the size of his crate and the space available on board. Either way, be sure to label his crate properly, make it comfortable, and attach a water cup.
Don’t forget to bring all of your puppy’s health and rabies certificates on international flights. These documents are required to cross most international borders.
