MEL-LHR - One flight??
on a RTW ticket, does the BA flight from MEL-LHR (via) SIN count as a single flight if you stay with the same flight number the whole way without a stop-over in SIN? i.e get the BA18. I know with this flight you would get 330 BA tier points as long as you dont take the stop-over (in which case you would get 2x 180 Tier points in F), so does it count as a single sector when calculating the 20 sector max, or is it still classed as 2 sectors?
