It would be nice if you could keep track of and periodically report not only luggage fees, but also pet in cabin fees and other assorted hidden costs. The charge to bring a cat on board in a carrier that will fit under the seat in front of you can be more than the human fare.
Your wish is our command! Actually, we've already done that and would like to take this opportunity to remind everyone that the links to all our handy-dandy fee and comparison charts are on the Airfare Watchblog page and right here on the Travel Q&A page. (Scroll down, look on the right hand side of the page for the list, and then click on the link for the chart that you need.) You can pick from our Frequent Flyer Fee Chart, our Baggage Fee Chart, our Miscellaneous Fees Chart, our Shipping vs Checking Luggage Chart, our Rule 240 Chart and our Flexible Date Search Comparison Chart!
