Question - Can we use our BX1B awards to book an open-jaw? For example, I leave LAX > JFK on the red-eye 1 June and return JFK > LAX on 1 October? I saw in the T+C that it cannot be booked as a multi-city ticket or a ticket with an open return, but saw nothing about an open-jaw.
What you describe is not an Open Jaw. It's a simple roundtrip.
