Most of the major airlines have had fare search options on their Web sites for some time now. Continental, however, has recently added a new advanced search function to its site. By using the new feature ( http://www.continental.com/fSearch.asp ) OnePass members can not only search for the standard low fares, but can set their preferences to find those fares that qualify for the most OnePass bonus promotions or mileage upgrades.
By using this optional search criterion, Continental will remove the results that do not qualify for OnePass promotions. Of course, no Q, S, T or L fare classes will appear in your flight search results, which may result in a higher total price for your trip.
