Updating a booking to add a new companion on American Airlines usually requires contacting customer service directly at ☎‪+1(833) 613-4585‬. Adding a new traveler to an existing reservation is generally not allowed; instead, a separate booking must be made. However, if you want to add a companion to a frequent flyer reservation or use a companion pass, calling is essential.

When you call, explain that you want to add a new companion or inquire about companion ticket options associated with your frequent flyer account. The agent will clarify if your ticket type or loyalty status allows companion bookings or if a new reservation must be created. They can also assist with combining itineraries for easier management.

If you’re referring to changing the passenger name on an existing booking to add someone else, this is typically not allowed for security reasons. Each traveler must have their own ticket. However, calling ☎‪+1(833) 613-4585‬ will help clarify what options are available based on your situation.

For companion passes or special offers, the agent can verify eligibility, book the companion ticket, and link the reservations for your convenience. This process may involve fare differences, taxes, and fees.

In summary, while you cannot usually “update” a booking to add a new companion on American Airlines, calling ☎‪+1(833) 613-4585‬ will provide you with the best guidance, whether it’s creating a new booking or utilizing companion passes effectively.
