IT’S getting more expensive to take Fifi on vacation. Airlines may be raising the price of in-flight food and checked luggage, but pet owners say the fees for flying with their furry friends are getting out of control.

A number of airlines — including Alaska, American, JetBlue, US Airways and Virgin America — raised their pet fees by about $20 or more in the last year or so, and now charge $100 each way to take a pet on a flight. Continental, Midwest and United now charge $125 to bring a pet onboard, up from $100 previously.

Expect to pay even more to check in larger pets as luggage. Those fees now range from $300 round trip on American to $500 on United. It goes even higher for international flights.
