I still think they'd do better running 3/4 daily to LHR and 2/3 daily into LCY. I'd have thought they'd jump at the chance to use some LHR slots on more lucrative routes. At the minute we have:
NCL-LHR
BA1321, 07:35 Mon-Sun (08:05 Sat)
BA1325, 09:35 Mon-Sun
BA1327, 12:05 Mon-Sun
BA1333, 14:40 Mon-Sun (14:20 Tue, 15:50 Sat)
BA1335, 17:10 Mon-Sun (17:30 Mon, 16:25 Sat)
BA1337, 19:40 Mon-Sun (ex Sat) Night stops
I'd suggest scrapping BA1327 and BA1335, leaving *roughly; 7, 9, 2 and 7 o'clock departures and adding something like:
LCY 07:00 - 08:15 NCL 09:00 - 10:15 LCY
LCY 16:00 - 17:15 NCL 18:00 - 19:15 LCY
LCY 19:00 - 20:15 NCL *07:00 - 08:15 LCY
