I have some EK points expiring end of March 2007. I can send Starwood points into my EK account. I am looking to book DXB to AMM and DXB to BEY roundtrip in any class. My dates are not set. Can I make date changes without cost? Does EK have one-way awards? Has anyone tried to use EK points to book one of their US partners? How was the experience? Is there decent call center support in the US? Thanks.
