Interesting to see the 2 hour transit time built into the LCY-JFK leg when you compare with the LHR-JFK leg.

Whats with all the interest with a lounge in LCY? There is no room for a lounge in LCY unless it is some broom closet that someone finds.

I suspect the main draw-back is no arrivals lounge at LCY to shower and change into work gear an d have breakfast for the earlier arrival flight in LCY. The arrivals lounge is far more important on a JKF-LCY/LHR flight so you get to maximise your sleep time on the short flight.
