We do have some Dutch FO's who commute from AMS. Most of BA's shorthaul involves 'tours' (nighstops) some of which are up to 4 nights away. But you will end up with the odd day flight in your roster, plus when you start a tour on an early you will have to come over the night before.
Its the 74/76 that does the LHR-AMS at the moment, but next year I think the A320 will be operating it as well. Although you could ask for a preference for AMS trips and nighstops, in BA you will never get a full roster of these trips .... maybe a few nights in AMS per month ...
BA has a lot of crew's who commute to work by air (probably 30% of long haul crews do).
I am contemplating moving back to NL myself, the plus point is that the route is very well serviced by BA/ British Midland and KLM.
But you should resign yourself to a few nights per month in a hotel at LHR.
(BA stby ticket LHR-AMS-LHR around £45)
Their are 'rooms' in houses run by crews as a business across the road from the report centre, these are around £25 per night (clean, self catering place).
On long haul with mostly later reports and only around 4 trips per month no problem, but resign yourself to up to 4-7 nights per month in the UK on shorthaul to start with.
A room in a shared house say in Windsor or London will cost around £350 per month.
Your own appartment around £600-£750.
Do you work for Martinair ????
Good Luck !
