Regular readers of this blog are aware that I am not usually a big fan of endorsing other sites, as I do not want to be perceived as partial or prejudiced as to other offerings.
However, questions concerning traveling with pets and particularly specific airline rules are a constant concern of animal lovers.
I was recently directed to a site that provides valuable information of airline guidelines for these issues.
Go to www.travelinsurance.org (no I am not endorsing travel insurance) for detailed information of airline policies regarding traveling with animals and even some requirements of countries outside of the U.S. borders.
