This is my first RTW trip and I need some help. I have not found the OW website very intuitive to use.....although with time on it I suppose I would get better. For one thing, I cannot figure out how to actually sign-in to the OW website!!

Anyway, I have some SWU's that are expiring at the end of Feb and I want to make use of them. Also, I am going to have a busy (not busy with travel)
Mar/Apr/May so I decided a RTW in Jan/Feb will be the most cost effective way to use up the SWU's, earn lots of points early in the year, and get to see some of the world (asia) that I have not been to before.

My tentative planned itinerary is as follows:

Jan 17 MIA-DFW-LAX on AA
Jan 18 LAX-NRT-HKG on AA & JL
Jan 22 HKG-BKK on CX
Jan 27 BKK-LHR-BCN on BA
Jan 30 BCN-LHR on BA
Feb 4 LHR-LAX on AA
Feb 5 LAX-MIA on AA

Please critique my itinerary and let me know if I am breaking any rules and also if there are other ways to further maximize miles on the US portions of the trip. Also, what should I expect this trip to cost me in D class? BTW, I use EF and that is my resource to choose AA flights that have upgrade inventory. I plan to use SWU's on the LAX-NRT, LHR-LAX, and LAX-MIA segments.

Thanks in advance for your help!
