On that screen, if you click each flight number you should get a popup. The last line of the table is the "selling class" or booking class for that flight. You should then be able to use the ba.com calculator to tell you the number of Avios and TP you'll earn for that flight, bearing in mind the airline whose flight number is being sold. (In your example, you're looking for British Airways throughout because you're flying on BA flight numbers on every sector, even though some are operated by other airlines. But note the
exceptions listed on ba.com.)
