Hi,
We have indeed made a few changes to ba.com today. The most noticeable will be the new header we've introduced across the site. We are currently showing this to a percentage of the customers using ba.com - which is why not all of you will be able to see the change for the time being.
The new header has a darker background and a white British Airways logo, so if you're seeing that - you're seeing the new header.
We'd love to get your thoughts on the changes to the design - so please post here if you have any feedback.
Thanks,
Gavin
