Tax & Fee Refund After Flight Change
 

I had three tickets booked from Europe to the US in J. The LHR-PHL was on BA, the fees per person around $400. A schedule change forced to route now via LHR-DFW on AA. Typically the fees on AA flights from Europe to the US are much less around $150 or so. It only occurred to me after I hung up and I did not ask the agent at the time. Does AA refund any differences in fees in these circumstances? Do I need to call or does it happen automatically?

The taxes are the same. The majority of those will be the high-end APD for the J tickets.

BA charges fees while AA does not. Your ticket should be refared and that will lead to a refund of those fees. Easiest to claim this via webform. Be careful about comingling the terms "taxes" & "fees"

I submitted a refund request via the AAdvantage Customer Service web page here: https://www.aa.com/i18n/customer-ser...er-service.jsp

It took about 5 days for someone to reply from AA stating that the refund department will review the request. Another five days later I received email notifications that the refunds had been processed. I received $225 per ticket back (out of ~$400).

I had a flight changed from flying BA DFW-LHR to an American AiIrlines flight and AA told me I need to wait until after my flight is completed then submit a refund request. I paid a surcharge of about $600 per ticket on the BA flight.

I tried submitting the request online and also calling.
