Please bear with me as I am new to this site. I have searched a bunch, but still have some questions.

I am flying CX (BOS-HKG) next week for the 1st time. I then fly CX (HKG-NRT) a week later, JL (NRT-PEK) 5 days later and then CX (PEK-HKG-BOS) as my return and all in Business. This is my 1st true International flight as well and looking forward to seeing the difference between domestic and international first hand.

I am currently unable to sign up for AsiaMiles and MPC due to ongoing site issues, but wondering if I really need both. The big thing I want to be able to do is accrue miles within OneWorld to hopefully use these miles at a later date. I am less concerned about Status as I won't be flying CX again this year. Plus, I have read about the mileage reset at each level so although I should get a high status after this trip is sounds like I will be bottom tier regardless.

So AsiaMiles is all I really need to get signed up for right? Can this be done at the airport prior to takeoff?

I am bringing a comfortable change of clothes for the flight, but if there were one or two other things I should do \ bring what would they be?

Oh, I am already preparing for a bad lounge experience at Logan before taking off.

Thanks in advance,

Scott
