Q. Can I use miles to upgrade any reservation through my travel agency or corporate travel desk?
A. At this time, you may use your AAdvantage miles to upgrade British Airways and Iberia flights as well as American Airlines codeshare flights operated by British Airways and Iberia which have been booked directly with American Airlines (via Reservations or AA.com).

However, British Airways and Iberia flights booked through other sources are not currently eligible for an upgrade using miles because of technical issues regarding systems compatibility. We hope that the inconvenience is more than offset by the opportunity to use AAdvantage miles to upgrade on British Airways and Iberia flights. We are working to expand upgrade opportunities to include to reservations booked through travel agencies and corporate travel desks. As always, you may use miles to upgrade American Airlines marketed and operated flights when booked through a travel agency or corporate travel desk.
