You already have flexibility with the Starwood Preferred Guest program. You can transfer to about 34 airlines, including Delta.
American Express Membership Rewards transfers to 16 airlines (including Delta), 4 hotel programs.
Citi ThankYou Rewards transfers to 11 airlines (not Delta), 1 hotel program.
Chase Ultimate Rewards transfers to 6 airlines (not Delta), 3 hotel programs, and Amtrak (which might leave soon). The value at Chase is not flexibility, their program is disappointing in that regard, it's primarily access to United Airlines and Hyatt Hotels.
