unfortunetly i think your out of luck. its on the website that they charge $20 fee for calling:
Q: Are there any charges associated with tickets issued by reservations offices, airport locations or American Airlines Travel Centers? A:
AA Reservations- A $20 USD charge applies for locations in the U.S. Puerto Rico, Mexico, Latin America, the Caribbean and Bermuda. (Due to government and market requirements, a higher charge may be charged in Colombia and Chile.)
- A charge of $20 USD will also apply when our reservations representatives assist with voluntary itinerary changes when the reservation was not created by American Airlines Reservations or on AA.com.
- A service charge may apply for tickets issued through locations in Europe, based on your reservation details
I booked with direct air out of RFD for my aunt to punta gorda and
didnt realise that they charge $10 for booking online, but there it was on the website.
