I am new to this and am trying to plan a 6 night trip to Tokyo. I have 100,000 American Airlines miles, 50,000 American Express Membership Reward points, and am planning on using one Hilton AXON reward stay and two nights from either the Citi Hilton Reserve or Hyatt cards for the hotel portion. I can easily get Hilton points and am therefore mainly interested in the airfare. I would like to go business class at least. I know in November American offers off-peak award to Japan for 50,000 one-way.

My question is, if I use the 100,000 American miles to get out there what is my best option to get back? I was looking into the United card, and the Sapphire Preferred but that is only 90,000 miles. Is there any way to book one ticket using my Amex Membership Reward points on an alliance airline and another on United? Or any suggestions for how I might get that extra 30,000 for the two United tickets? I was planning to apply for the United and Sapphire Preferred together. Any other suggestions? Also, any recommendation for places to stay? I was thinking I would use Citi Hilton Reserve for Hilton Gold, do a Hyatt Diamond match then get the Hyatt card for two nights in a suite.

Thanks so much!!
