My fiance and I are looking to fly to Thailand from New Orleans. I have 3/4s of the miles (~350k) I need to get there on United and have almost a million AMEX rewards points from which to draw. I understand that AMEX and United are not partners. i would prefer to use my United Miles up as I am switching over primary airline affiliation to Delta given my location in New Orleans. Can someone tell me the best way forward to make this trip work? UPDATE: Should've mentioned that would ideally travel business or first and in October which is why I think I'd need the extra 100k miles or so.
