Q. Is it possible to find an inexpensive walk-up price for any airlines these days? I'd like to fly to San Antonio in the next few days to visit a sick family member and flights are over $500.

A. Walk up fares are far from cheap, so you might give Priceline's Name-Your-Own-Price a shot. We've managed to score some pretty terrific fares for last minute trips, even when booking the day before departure. Before placing your bid, Priceline provides the current going rate along with recent winning bids from other users, which is pretty helpful. If your bid isn't accepted, you'll be asked to change your search parameters - such as the number of connections you're willing to make, or choosing nearby airports, before eventually raising your bid. Chances are you'll find something for much less than $500.
