Some unpleasant unforeseen rule changes today - Intra-South America O/D O/J prohibited, and no transit through origin point.
C/ TRAVEL MAY ORIGINATE AT ANY POINT FOR WHICH FARES ARE PUBLISHED AND MUST TERMINATE AT THE SAME POINT EXCEPT THAT ORIGIN-DESTINATION SURFACE SEGMENTS ARE PERMITTED AS FOLLOWS /1/ WITHIN THE COUNTRY OF ORIGIN /2/ WITHIN THE MIDDLE EAST /3/ BETWEEN THE UNITED STATES AND CANADA /4/ BETWEEN HKG AND CHINA /5/ BETWEEN MALAYSIA AND SIN /6/ WITHIN AFRICA D/ TRAVEL MAY NOT BE VIA THE POINT OF ORIGIN.
No DAC//SIN-BKK either, but not sure when that went away.
The topic of eligibility of Lan carriers seems answered by this:
UNLESS OTHERWISE SPECIFIED . NOTE - FARES ONLY APPLY ON ANY AA/AY/BA/CX/EG/IB/JC/JL/ JO/KA/LA/LP/MA/NU/QF/RJ/XL/4M FLIGHTS
so no new problems there. No mention of the 16-segment rule but these jack-in-the-box rule changes do not inspire confidence.
Also fares ex-USA have gone up in some instances, AONEx by $1000 - $2200 depending on no. of continents, DONE3 and 4 unchanged (so far) and DONE5 and 6 up by $300 and $700 respectively.
