What are examples of applying the passenger fee on or after Dec. 19, 2014, if air transportation is changed?

 

Example 1: Air transportation from Washington to Chicago to Los Angeles with a stopover only in Los Angeles that returns via the same route purchased before December 19, 2014, is charged a $11.20 fee for two one-way trips. If the passenger changed the itinerary to Washington to Los Angeles with only a stopover in Los Angeles and returns via the same route and the ticket is re-priced on or after December 19, 2014, the carrier must continue to charge the September 11 Security Fee of $11.20 for one round trip. 

Example 2: Air transportation from Washington to Chicago to Los Angeles purchased before December 19, 2014, is charged a $5.60 fee. If the passenger changed the itinerary to Washington to Los Angeles with a stopover in Los Angeles and returns via the same route and the ticket is re-priced on or after December 19, 2014, the carrier must charge the revised September 11 Security Fee of $11.20. 

Example 3: Air transportation from Washington to Chicago to Los Angeles purchased before December 19, 2014, is charged a $5.60 fee. If the air carrier changed the itinerary to Washington to Los Angeles on or after December 19, 2014, neither the carrier nor the passenger is liable for a revised September 11 Security Fee. The fee remains $5.60.
