Q. I have a 6 pound, very quiet, chihuahua  that we would like to take with us when we fly. Can he go as carry-on luggage in his own tiny carrier which would fit under a seat, without being charged extra? If not, what is the difference between a quiet behaved pet verses a child sitting on a parent's lap?

A, Unfortunately, the airlines don't lower fares for good behavior. You'lll end up paying as much as $80 each way for your pet, depending on the airline. And you bring up a very good point about the lap child. Perhaps airlines should add a surchage at the end of the flight if a lap child has been rowdy!

Q. My friend and I had a great time in Europe this past summer, but I was unable to exchange my Euros for Dollars before we came back to the States. We have about 500 Euros left. What is the cheapest way to exchange them for U.S. Dollars?

A. Your best (and cheapest) bet would be to exchange them at your bank. This is a service most banks provide exclusively for their own account holders, but some banks will exchange foreign currency for the general public.

And while Euros are a snap, some currencies are a little more difficult to exchange. For example, if the folks at the Forex counter in Whoville won't take Romanian Leis, we suggest placing a call to the Consulate General where they should be able to direct you to the nearest place that will.
