On que the trope that was BAW LCY-JFK raised its head...
Desk to plane to desk..."Speedbird One" ala Concorde `an all that.
Largely commercially flailing misconception by BAW at LCY provided by an a/c without the performance hidden by a pre-clearance fuel stop at SNN.
Already winding down but its final demise unannounced BAW breathed a huge sigh of relief when they could eventually can it.
Quote..."You`re also often expected to work the full day in London before flying out"...Ah... back in the day then that accounts for a proportion of the evening EOS pax at STN...never would.
