American Airlines to Introduce Cashless Cabins Onboard U.S. Domestic and Canada Flights
Tuesday February 10, 11:00 am ET
FORT WORTH, Texas, Feb. 10 /PRNewswire-FirstCall/ -- American Airlines will begin this summer to transition to cashless cabins onboard flights within the United States and to and from Canada. On these flights, American, a founding member of the global oneworld® Alliance, will only accept major credit cards or debit cards for onboard purchases such as headsets, fresh light meals, snacks and alcoholic beverages.
"Moving to a cashless cabin allows us to streamline the inflight sales process for both our customers and flight attendants," said Lauri Curtis, American's Vice President - Onboard Service.
Flight attendants will use a hand-held Onboard Sales Recorder to charge credit and debit cards, eliminating the need to search for small bills or change. The airline has been using these user-friendly devices since May 2006. American Express® and other major credit and debit cards will be accepted. Receipts will be provided to passengers upon request.
