KLM seems to have no
non-stop flights between AMS and
MIA in 2009.
But the Dutch carrier
Martinair,
based at
Amsterdam Schiphol airport
has a long tradition of flying between Amsterdam and Miami
(MIA).
But Martinair has ceased to exist. After this KLM started to fly
the route, and KLM was still flying the route in january 2012,
but it seems KLM might abandon the route.
There are American carriers serving this route in 2011.
