1. Read the fare rules and routing rules for PRC90, to make sure your trip qualifies for that fare basis in terms of min/max stay, advanced purchase, etc. If all requirements are satisfied, moved to step 2. If not, do the same for the next fare basis (PRC906, PRC907, for example).
2. Look into flight availability for the round trip availability. Look for the entire trip as a whole rather than breaking it up, as there may be married segments logic. Note the dates with P space available. If P is not available on the dates you want, try Z, and go back to step 1.
3. Call AC or travel agent, quoting the fare basis you find in step 1 and dates in step 2.
4. Good luck, ticketing is complicated, EF doesn’t work 100% of the time, agent may not be knowledgeable enough, etc.
