http://www.startribune.com/lifestyle/travel/122310274.html It's more complicated - and expensive - than ever to fly with your four-legged pal. These tips can make it less troublesome. Summer vacation is no longer just for two-legged travelers. Room service menus for Fido, massages for overstressed terriers and tabbies, cushy beds for canines: Many hotels have been ratcheting up the pet amenities. Best Western has even hired Cesar Millan of National Geographic Channel's "Dog Whisperer" to be the chain's pet travel expert. The problem is getting your pet to the destination. In recent years, transporting pets on commercial flights has grown more complicated -- and expensive. All major carriers have significantly raised the fees for bringing pets onboard, matching, or in some cases, surpassing, the $100 surcharge each way they typically charge for children flying alone. Fees vary depending on whether the pet flies under your seat, or as checked baggage or cargo, which involve extra handling. American, Delta, United and Continental charge $125 each way for pets in the cabin. United charges the most for pets traveling as checked baggage: $250 each way or $500 round trip.
