I want to change to the same flight and destination, but a different date. The 2 reward seats in Club World are available for the new date. The “change flight” button gives me the option to change to a different date, but I am nervous about pressing that. What happens next? Does it give me the option to put in the new date, and show me the flight options I can choose? And then confirm the change?
is it really that simple?

I guess with all the IT problems BA has been having it is hard to expect that this will work. Thanks for any reassurance you can offer.
