Airlines take flying live animal cargo very seriously. So seriously, that they refuse to fly a puppy if the temperatures will be outside of 20°-85°F. In the summer months they will just stop all live animal cargo flights to certain areas of the United States because it is just too hot. Places like Arizona, New Mexico, Southern California will be embargoed. The point of this isn't necessarily that a puppy cannot thrive above 85°, it is an acclimation issue. Although it can feel inconvenient when the temperature at the airport will be just barely over 85°, but it is always for the safety of the puppy. You can visit www.aacargo.com to find out more.
