If it’s on one ticket book it and go. If you miss the connection they will rebook you and you might be due compensation. Even if your not due compensation a polite email to their complaint department might get them to throw 10,000 miles at you. Don’t be afraid if they are rebooking you to request the next flight regardless of operating airline. They will auto rebook on their partners but you might get them to move you to a earlier flight on another carrier.
