Hello

If I wanted to fly uk-AMS-elsewhere, but have a few nights in AMS going one way, would it be possible to buy two round-trips, one uk-AMS, the other AMS-elsewhere (both sets would be KLM)?

Following on from that (and this may be the sticking point) could I combine the two sets in one direction (allowing the AMS minimum connection time), or would this mean I'd have to collect luggage in AMS and re-checkin?
