BA LHR Route
I never realised how popular the NCL-LHR route was!
Just looked on thebasource.com for Septembers available seats (I had some spare time) and in September there was 49196 seats available with passenger figures of 43782 for that month. This gives an impressive 88.9% load factor and that was with around 20 of the 160-odd flights being a 188-seat A321 and 70 being a 162-seat A320
Travelling on the route in February and was expecting maybe 70% at best (with maybe a seat to myself!) but these figures seem pretty good for the route! Does it get quieter in winter months or is it always this busy?
