After a full week of research for options and 2 days worth of calling I managed to book the following itinerary for myself and the parents in May/June 2015
Me: HKG-(CX F)-LAX-(AA J)-YVR-(CX J)- JFK/LGA-(AA F)-MIA -(AA Y)-ORD-(CX F)-HKG [Stopover at YVR, destination MIA]
Dad: HKG-(CX F)-LAX-(US F)-PHX-(US F)-YVR-(CX J)- JFK/LGA-(AA F)-MIA -(AA F)-ORD-(JL F)-NRT-(CX J)-HKG [Stopover at YVR, destination MIA]
Mom: HKG-(CX F)-LAX-(US F)-PHX-(US F)-YVR-(CX J)- JFK/LGA-(AA F)-MIA -(AA F)-ORD-(JL F)-NRT-(CX J)-HKG [1.5 days transit at LAX, Stopover at YVR, destination MIA]
Cost is 120,000 miles each plus approx US$100 in taxes and US$50 for booking fee
Mom and dad are travelling from HKG so the booking is perfect for them, however as I am travelling from SYD, I had originally tried to book this as a SWP-North America award but without success. My original booking included SYD-HKG/HKG-ADL-SYD portions of the trip but was not able to get it ticketed as I was quoted as busting MPM every single time.
It is worth noting (nothing new to everyone, I guess), each US Airways agent had very different interpretation of rules and it is all down to luck as in whether you are able to ticket your booking:
Call 1 (Duration 1:30) - Called to put Mom and Dad's ticket on hold (on separate booking as miles coming from 2 accounts). Originally wanted to book HKG-LAX-PHX-YVR-JFK/LGA-MIA-JFK-LAX-NRT-HKG, but agent wouldn't book MIA-LAX via JFK and insisted to book it via CLT (ie flagship AA F services on A321 JFK-LAX vs US Airways F). Agent also claimed that stopover is not permitted at YVR as it is within the same zone of destination (incorrect). Asked agent to save booking and HUACA
Call 2 (Duration 00:58) - Placed my initial itinerary on hold SYD-HKG-HND-SFO-LAX-PHX-YVR-JFK/LGA-MIA-JFK-SFO-HND-HKG-(CX Y)-SYD (<24 hour transit in HND and HKG), asked to ticket but agent quoted MPM. HUACA
Call 3 (Duration 00:14) - Found J availability on HKG-SYD via ADL on CX, asked to change and ticket but again quoted MPM. HUACA
Call 4 (Duration 00:33) - Asked to ticket my reservation but again quoted MPM. Agent quoted MPM again and had to change outbound to go SYD-HKG-LAX-YVR, and return to MIA-ORD-HKG-PER-SYD instead as agent said you can only have a maximum of 4 segments per journey. Asked to ticket again after the change but still unsuccessful. HUACA
Call 5 (Duration 00:15) - Had an agent with very strong Southern accent, asked to CHANGE my parent's booking but after reading the booking ref for my dad to the agent, the agent cancelled the booking. I immediately said this is not what I have asked for and the agent claimed the the booking has then be re-instated (and of course impossible to retrieve online anymore). When I queried and said I cannot see the booking online, the agent became upset and said "Are you saying that I am lying, sir?" with a very unfriendly tone. I kept pressing on the issue and the agent just then transferred me to internet helpdesk - who obviously wasn't able to help. HUACA.
Call 6 (Duration 00:18) - Rang to try to book Dad's itinerary again, but agent was unable to see JL availability (even after prompting to look at a different place), and refused to hold the booking. HUACA
Call 7 (Duration 00:23) - Managed to find the best agent ever for the past 2 days who was brilliant and re-booked Dad's itinerary. The agent was happy for me to read the flight numbers to her and absolutely knew what she was doing. Unfortunately wasn't able to get her to ticket as the tax was taking forever to come up and I had to head out for dinner
Call 8 (Duration 1:56) - Great agent (thank god!), managed to change Mom's itinerary to match Dad's itinerary except for the outbound, asked to ticket both Mom and Dad's ticket and succeeded (but took over an hour for the tax and mileage to calculate). After the two itineraries were ticketed, I tried my luck as well to also get the agent to ticket mine as well. Again it took forever but again was quoted MPM. At this point I am pretty convinced that I won't be able to book my YVR/MIA trip to originate from SYD and go via Asia, so I decided to ask the agent to chop off the Australia-HKG segments and ticket as North Asia-North America award. Finally succeeded after almost 2 hours of call.
All in all it took me over 6 hours on phone (thank god to Skype - or I will be broke by now!) with the US Airways agents and I swear I will vomit if I hear those holding music on US Airways again. Quite happy to have the itinerary booked as it is but would prefer if I can also get a JL F segment in my booking (and change MIA-ORD to F when it becomes available). May try to change my booking closer to the time and see what is available. Pretty happy for now and I have the rest of the arrangements for the 4 week trip to worry about now! Hope this is helpful for anyone who is looking to book a US award
