There is probably a simple explanation that I have overlooked but, on a forthcoming KLM flight, I am getting a very different availability seatmap from EF than I am from the KL website itself.
The flight concerned is flight KL887 from AMS to HKG on April 3rd in business.
KL tells me that only 2 seats are still available (6G and 6K) whereas EF tells me that, in addition to these two, there are also another 8 seats free (2DGHK, 3AGH and 4A).
