Airline Ticket Pricing: How to “Beat” the System

Travel ticketing is an industry, but creatively finding and booking the lowest fare is an art.  Ticketing agents like Kayak and Priceline have enabled the comparison shopping of flights, but only the most sophisticated bargain hunters understand how to book “phantom flights” in order to cheat the system and obtain the lowest possible fares.  Ironically, these users are leveraging the airline’s very own discriminatory pricing policies in order to identify system booking ploys and obtain these low fares. 

In one type of booking ploy flyers can use a “Hidden city” in order to obtain a lower fare on a route to a hub city.  For example, instead of booking a direct flight from San Francisco to Dallas/Fort Worth (DFW), a flyer can save $400 by booking a flight from San Francisco to Austin via Dallas/Fort Worth (just remember to get off the plane in Dallas…). 

Another type of booking ploy leverages “Round Trip” discounts.  Airlines try to segment customers and charge business travelers, who often book one-way tickets, higher fares than leisure travelers.  Thus, one-way ticket prices are sometimes heavily overpriced in comparison to the round-trip fare.  For example, on a flight from Buenos Aires to Atlanta, a traveler flying one-way could save over $1,100 dollars by booking a round-trip fare vs. booking the one-way fare (chart below). 

While both the “Hidden City” and “Round Trip” booking ploys are strictly forbidden by airline ticketing policies, there is very little press of flyers being penalized for such activities (i.e., airlines do not go after violaters).  From the customer point of view, flyers on forums promoting these activities often express feelings of justification for having taken advantage of these loopholes.  In a recent NY Times article titled How to Beat Low Fares, Nate Silver said that flyers confronted by airlines of ticketing fraud should “proudly state that you’re doing your part to help the airlines understand the inefficiencies in their pricing structures, and that you’re bringing exorbitant fares more in line with the free market.”

While I do not want to debate the morality of booking phantom legs, I could not disagree more with Nate Silver.  These discriminatory pricing tactics employed by airlines reveal their sophistication and acute understanding of the marketplace.  If these tactics did not exists, then some travelers, who are willing to pay more for flights, would not be paying higher prices.  Thus, prices across the board would have to increase, not decrease.

    I like the phantom leg/hidden city idea. But I have always heard from the airlines that if you missed one of the segments in your flight, the round-trip piece is canceled. So in your example, if I did get off at DFW (the hidden city) on my way there…a) would I even be able to get on the round trip flight back or would I lose the entire segment of the way back and then need to buy a one way? b) if so, would I need to originate in Austin instead of DWW?

    Thanks for very interesting article!

      You are correct that airlines cancel all remaining segments in a trip if one misses a flight. Thus, this type of buying scheme only works for one ways or the last segment of a round trip. Also note, any bags checked keep going to the destination. Airlines put these type of restrictions in place in order to create artificial price barriers for travelers.

      Thanks for your comment!

    Also, sometimes it’s cheaper to buy two one-way tickets (on different airlines) than try to book one roundtrip.
