American Airlines has now made both Royal Air Maroc and Etihad awards available for bookings on its website.
Royal Air Maroc became Oneworld members back in April, and Etihad has been AA’s partner already for years.
You can access AA here.
Here’s the search I made for GRU-BEY:
There are options with British Airways, Royal Air Maroc, Etihad, and Royal Jordanian (or combinations with them).
Here are the airlines now bookable on AA’s website:
Note that Etihad is not on this yet while Royal Air Maroc was added yesterday, but both awards do come on the general search.
There are still few airlines that you cannot book on AA’s website, such as GOL, which became a partner (again) after LATAM exited the alliance.
I hate having to call award reservations in. It is much easier to do them, when possible, online. I am glad that AA has slowly expanded the airlines whose awards are bookable on its website.
