American Airlines Finally Provides Domestic Refunds Electronically (No More Paper Vouchers!)
by Gary Leff on November 28, 2019

American Airlines has begun issuing evouchers for domestic refunds (50 United States, U.S. Virgin Islands and Puerto Rico) instead of giving out paper vouchers. Paper vouchers were challenging because they could be more easily lost, and if you didn’t do your ticketing at the airport you had to mail them in – and hope they wouldn’t be lost in the mail. Ticketing wouldn’t occur until the voucher was received.

Customers can check the status of their refund on prefunds.aa.com and will see that an email has been sent

The email will contain the voucher and PIN.

American still uses little green pieces of paper for international refunds. — link to article on View From the Wing
