Hello again,
Just got back and here´s how it went.
Checked in at Abz and was asked if assistance was required there, thank you but no.
On descent into Schipol CC contacted us to say the golf cart would be waiting.
Leaving the aircraft the same CC passed us to the assistance team who whizzed us to our departure gate passing through security and Passport control on the way.
On approach into Bilbao the CC asked if we required assistance on arrival. Again it was thank you but not necessary.
The whole thing was handled efficiently and with courtesy. The KLM CC were fantastic on both legs of the trip.
Nothing but praise all round.
