One day later ex-HKG, of course.
BA27/28 started out as all 772 when the A380 arrived and is slowly increasing to all 773. I suppose for fleet planning reasons they tend to be the same aircraft on the same day each week, but the number of days featuring the 773 is slowly increasing. I wouldn't want to bet my house on which days show up with a 773 as they do change around a bit.
