what would happen the other way around? Price for US-AMS is the same as US-AMS-EU and I'm not sure if the 8h layover in AMS would be enough for +1 to see the city. So I'm thinking of just booking US-AMS-EU and then decide a couple weeks before departure if we want to stay longer in AMS or not. Can the helpdesk cancel the last segment or should I just do a no-show?
