Dear username
We're writing to let you know about important changes to your booking on flights operated by US Airways.
As you may be aware, US Airways and American Airlines have been in the process of merging into one company. They will complete the final stage of their merger over the next few months, which will see all remaining US Airways flights being transferred to operate under the American Airlines brand.
This means that your flight will now be operated by American Airlines and that the flight number will change to an American Airlines flight number.
In the next few days, the teams at US Airways and American Airlines will start to make the relevant changes in their reservation systems. During this 'booking migration' period, you may notice some changes to your booking on ba.com that could indicate that it is not confirmed or that it has been cancelled.
Please do not be concerned as this is part of the process required to make the changes in the system. Once this process has been completed on 22 July, you will be able to obtain your revised flight details at Manage My Booking.
If you have access needs and have requested additional assistance for your journey, we'll make sure we transfer your requirements into your revised booking.
Warm regards,
British Airways Customer Service
Stay tuned. Have a bunch of USAir flights coming up. Bolded by me.
