Not sure if proper etiquette is to post to this existing thread in obsolete forum or create new one in consolidated forum, but I'm assuming that the PMCO 24-hour cancellation coding hasn't changed and have a few questions that PMCO flyers can best answer.
I have a reservation that apparently is going to take 24 hours to be ticketed because of one segment on a partner that requires the delay. Do I only have 24 hours from booking to cancel it or will the clock start once it's ticketed?
I see that you can't request upgrades online until after the itinerary is ticketed, but can you do that over the phone? (R space is currently available, but you never know if it'll still be there later.)
In general, if you make a free change to your itinerary within the 24-hour window, does the clock start again? If not, presumably you'd want to cancel entirely and start with a new res.
