One can already fly CWL/JKF (wherever the f*ck JKF is
, CWL/India, CWL/China etc. etc. etc. via the KLM link.
What would make for interesting reading is a breakdown of ultimate destinations for CWL's KLM punters .... and I'm guesstimating that the numbers travelling CWL/NYC, CWL/India, CWL/China etc. wouldn't even fill a once weekly turbo-prop sized service!
