Apologies in advance if this has been posted already.

The BA Travel Trade website has seemingly been replaced with BA Travel Partner Connect.

A quick glance suggests it’s an improvement. It seems to work ok on mobile and linking within the site seems to work better.

Some of the info has been tweaked, for example the ‘rebook any carrier’ policy within the cancellation guidelines seems to be better explained.
