I hear humans complaining about the airlines all the time, but I gotta say -- traveling just keeps getting easier for my ilk.

Partly that's because there are more of us traveling than ever before. According to the Transportation Department, about 2 million animals a year fly in the United States. Hotels are more pet-friendly (and there are even pet hotels) and airline policies more understanding. There's now even an airline devoted exclusively to meeting the needs of the four-legged set - Pet Airways, which seats pets not in with the cargo but in the cabin.

With all these pets jet-setting about, perhaps its no surprise to learn that more airports are now adding pet restrooms -- including Atlanta, Chicago O'Hare, Los Angeles, Phoenix, San Francisco, Washington Dulles and Washington National.

This is partly to come into compliance with a federal law aimed make airports to install facilities for travelers with service dogs, but its good news for all of us.

Now if only my collar wouldn't beep every time I go through security.
