the loads on BA's LCY pond-hopping services are nothing to write home about
I heard somewhere (sorry no source) that they were 70%+, maybe even 90%, or was that a different route - still at superb yields, especially as all biz.
When this route was first talked of, I wondered how they'd get round the tech stop, but that seems to have worked ok, and isn't a problem on the return leg.
I also remember EOS heavily advertising around Canary Wharf - all well and good, but clearly not good enough.
I'd struggle to think which other US cities have anything like the same need for such a service? I would guess IAD has some top ranking politicos, yes there is plenty of hi-tech stuff around the beltway, but the same as NYC? Chicago may be have more financials - still a big futures centre iirc, but are we still within range?
