How many member airlines are part of the oneworld alliance, including American Airlines?

The oneworld alliance includes a total of 13 member airlines, which is why this answer is accurate. This alliance is designed to provide its members with a range of benefits, including increased connectivity, shared frequent flyer programs, and access to lounges for travelers flying with any of the member airlines. Since American Airlines is one of the founding members of the alliance, the total count of member airlines also includes those that have joined since, bringing the total to 13. The structure of the alliance allows for an extensive global network that enhances travel options for customers of all member airlines.

Other choices may not reflect the current total of member airlines accurately as the alliance membership has changed over time, leading to some confusion regarding the exact number.
