Q. I’m responsible for tracking our company travel budget, but it gets confusing with all the extra add-ons now for various airline services and amenities. Is there a central location that lists these things airline by airline?

A. There are several. The popular travel buying site kayak.com has a handy chart at www.kayak.com/airline-fees that covers most domestic and some international carriers. Another provider of fee charts is Farecompare; check them out at www.farecompare.com/resources/airline_fee_table/index.htm. And the web site SmarterTravel has a downloadable pdf chart at http://i.slimg.com/sc/sl/graphic/u/ul/ultimate-guide-to-airline-fees.pdf.
