Sometimes it appears, but when you click on it, you mysteriously get the "Your payment is in progress" screen, as others have reported.

I've found the following link to be fairly reliable though: https://www.britishairways.com/trave...b/flightSearch

one way around this is to price up in itamatrix and use powertools to force it in to ba. this will usually get you in to the old booing engine but should price and allow you to book the flights you actually want.
