Hi, Here is the background. Daughter is flying Delta (booked by her school) from STL to HKG via Detroit(yes I agree - strange). Our home airport is ORD - they couldn't fly through here!!! Anyway, while I have her accumulating miles on AA and UA programs - these Delta miles would be orphans. So I was looking at options for which Delta partner airline might be best for her to earn miles for these flights. Since it will be a total of about 16,000 miles, the only one that looked possible for future use would be Hawaiian Airlines for some inter-island flights. Although, keeping these miles live until we use them might be a bit tough. Would appreciate any advice. Thank you!
