I have the following points:
60000 miles in Alaska
48000 miles in Emirates (16K expires end of April)
60000 points in Hilton
8000 points in Marriott
40000 miles in Delta.
110000 points in Amex platinum.

I am looking to book a ticket to MAA from SEA anytime in Jun through August for 7 nights (business class ideally). I have been playing around with miles and have been tying myself up in knots on the cheapest or best way to utilize the points/miles. Can someone provide suggestions/advice on how I combine the above and what airline would be best to book?

Thanks!
