If you don’t care about scoring an allegedly “$6000” flight by transferring to an airline for a business/first class, likely your best transfer is to Hyatt. It is for me. I also like transferring to Southwest on cheap fares, where you can get almost 2 cents apiece.

Remember that with Hyatt, room-nights on awards count for status. This is valuable. Hyatt Globalist is highly prized. Airline status is pretty hard to get and not worth that much for a lot of people.

You should consider getting the Hyatt credit card. One of the best out there. The free annual night for holding the card is alone worth more than the fee. And spending counts toward status.

Miles awards on airlines do not count for status.

A while back, Chase had a big bonus (40-50%) to transfer to BA Avios. Depending on your travel patterns/airport, if that comes back it can be a terrific value.
