Flights: Is personalization by airlines actually discrimination?

If you book an airline ticket through an online site or go to a travel agent, you get the ticket price and, thanks to recent U.S. Department of Transportation rulings, that price includes taxes and fees. What you don’t get — at least, not yet — is a price that includes ancillary fees (baggage, early boarding, seat choices), but consumer advocates are working toward that. But the changes in store for ticket booking may be even greater. Booking could be the all-new Mr. Toad’s Wild Ride. Or not.
