So my trip is almost ready to be ticketed. This is what I actually have in the system:

AA 887 D 10FEB 5 DFWYVR
CX 888 D 15FEB 3 YVRJFK
QF 008 D 19MAR 7 LAXSYD
QFOPEN D AKLZQN
QFOPEN D ZQNROT
QFOPEN D WLGMEL
QFOPEN D MELSIN
CXOPEN D SINBKK
CXOPEN D BKKHKG
CXOPEN D HKGKUL
CXOPEN D KULHKG
BAOPEN D HKGLHR
BAOPEN D LHRIST


Except they're still telling me that I can't have both SJU-JFK segments in there -- please note, this is after the fare and taxes have been calculated. I do intend to fly both of them -- I'm going to buy a one-way on my own to go down to SJU. This is essentially a mileage run, because I don't know what else to do with the extra segment.

I couldn't find anything in the OWE rules that prohibit me from taking the same flight twice. What gives? Any ideas?
