As Mwenenzi said, BA is your only non-stop option. Your 1-stop options are AC, UA, DL, B6, and AA. I'd probably rank those DL > B6 > UA > AC > AA myself. If you want any product which is demonstrably better than another though, you'd need to double connect and very likely use separate tickets (for something like SQ FRA-JFK or TK IST-xxx).
