After a LOT of reading (thanks to all the experts here and elsewhere that are so willing to share your tips!) and even more earning/savings of miles, I was able to find and book my first ever miles redemption. I found and booked the following itinerary on the CO.com website for myself, the Mrs., and our daughter for next July/August (107,500 miles each): SFO-ICN on UA in C, then ICN-HKG on OZ in C (stopover for 3 days) HKG-SYD on VS in C, then SYD-AKL on NZ in C (destination) AKL-SYD on NZ in Y, then SYD-SFO on UA in Y (not enough miles or availability to do the whole trip in C sadly, but the direct flight home won't be too bad in E+) My questions now are...what next? Obviously I wasn't able to select seats on the OZ, VS or NZ segments so I'm assuming a call to those three airlines is in order to do this. Will I need to get a confirmation number from each of those airlines to be able to check in before each leg, or can I use the CO confirmation (I doubt this)? What other steps should I be taking now to make sure this goes as smoothly as the booking process was?? Thanks in advance for any helps/tips/insight here.
