How to book BA Award seats

I’ve been searching for several weeks for a trip to Europe, looking to book using the BA Companion Certificate. For the last few weeks I have searched direct to a destination and not choosing to stopover in London. BUT, apparently through a few texts & phone calls with a friend looking to book the same, the trick to searching BA is to enter that you are choosing to stopover in London while on this 2nd page of your search screen:

Doesn’t really matter if you are stopping over or not. This will allow you more flight selection to your destination.

If you were to choose “No Stopover” above, your flight availability appears less available to your same destination…weird. But the ‘trick’ works.

Happy searching for a BA Award Seat!
