Interesting pricing anomaly found by Brett Snyder (Cranky Flyer) Anybody have an explanation? BRETT SNYDER recently ran an online search for flights from Washington Reagan to Dallas-Fort Worth to San Francisco and then back to Washington. He found something strange. If he booked the three legs of the flight as separate one-ways with American Airlines, the total cost was $412.80. But if he wanted to book the whole multi-city itinerary together, American was charging $1,837.20!!!! (Explanation points mine) I mentioned on another thread my namesake nephew's luck with an SEA-DFW-BHM and return same stops for Thanksgiving. Total was $400 round-trip.
