FYI:
CRS is canceling GT on the B/E DH even if no one has deviated. They saw one had a JS RSV back to base and the other a dev ticket home. They will get the GT back for you on request.
Even if both have deviated on the B/E DH, they will rebuild it if you arrive late and layover is not long enough before scheduled DH (change pairing to later DH)
