Hello. I am seeking advice on any pitfallsas in the following thinking. We want to fly from Phl to sfo on Alaska airlines using points from Amex. Then quantas from sfo to Sydney using Marriott miles, then air New Zealand from Christchurch to Honolulu using capital one miles and from Honolulu to lax and then to Phl using credit card.we would land in sfo at 11:00 am and fly out at 10:00 pm so I imagine they will leave enough time to make the flight in the event of a delay. It does mean using different sites to book the trip given the points are scattered. I know I can transfer them to Amex and have a platinum agent book it all but it could take up to 6 weeks to transfer some points and I would prefer not to wait. Thoughts?
