I need to know what rules should i follow this is the scenario
Passenger already took the departure last January 05 , and his return is February 20 . He called to change the ticket to FEB 11.
Here's the FARE RULES
BEFORE DEPARTURE PER DIRECTION CHARGE USD 150.00 FOR REISSUE/ REVALIDATION. NOTE - UPGRADE TO HIGHER FARE MUST BE TO THE HIGHER AVAILABLE CLASS IN THE FLIGHT DATE DISPLAY. AFTER DEPARTURE CHANGES NOT PERMITTED.
* GENERAL RULE FOLLOWS * BETWEEN THE UNITED STATES AND MIDDLE EAST FOR QA0RAAMP TYPE FARES
Do I need to follow the rules of after departure since passenger was able to take the Departure or I need to follow again the before departure?
