I have been Plat for 5 years straight, dropped to Gold this year and about to hit Plat again. This morning I was op-upped LCY-ORY, first time ever on either AF or KL. This route is jam-packed now, and has been ever since the Eurotunnel incident.
In fairness, the curtain was moved back one row and I was moved to a different seat in the same row originally booked...however whilst at the gate I saw the original occupant of my new seat get reallocated a seat right at the back of the bus
Of all the routes to get upgraded on, anything out of LCY is pretty pointless...no lounges, same seating, marginal catering difference. God only knows why people pay the premium they do for J class out of that airport.....
