As part of a pilot program to eliminate cash transactions at airport locations, AA is no longer accepting cash at IAH, and SAN will follow on March 11.
Passengers who only have cash will be directed to kiosks operated by Ready Credit, where they can exchange their cash for a prepaid debit card, subject to a $5 loading fee.
