We just had a timeshare in Oahu fall into our lap for the end of Sept. Apparently a friend of ours isn't using it and offered it to us. I have never been to Oahu. We are currently flying out of DTW or any airport that is relatively nearby PLN, CIU, TVC. I would like to go Business or First class. We would return from either KOA or LIH - it doesn't matter as we can switch our plans for hotels based on airline airline availability. At this point, it looks like it will be Delta that we fly but also looking at UAL. We have no elite status. My question is....are there any international flights from the US that make a stop in HNL. Secondly, would you choose UAL or DL for this flight? Thirdly, I have about 57000 DL points but a lot of AmEx membership reward points that I can transfer over. My thought is to get one award seat (for me) and then purchase my husband's seat with his AmEx Delta card. Delta's Business class is about 2K whereas UAL is about 3K. I'm concerned about burning too many points as we are trying to book a trip to SA and then a stopover in Scotland within a few weeks. I have 131,500 UAL, 260,000 UR and 245,000 AmEx. What are your thoughts?
