Booking Z fares - where are the fare rules published?
I'm trying to book a SFO-BKK-PEK-SFO itinerary the last week of February. I've gotten the SFO-BKK (via NRT) leg to price out with a Z fare, but can't get PEK-SFO on March 6 to price out with anything other than D/C. Company rules say Z fares only, so it's no-go.
The flights show Z9, so I suspect I'm not meeting the fare rules rather than there being no seats available. Question: How can I find all the published Z fares applicable to a city pair, along with the fare rules? If I can find the fare rules I might be able to adjust my travel so I fit within them.
Thanks in advance!
