Norm--your problem wouldn't be connection time, so much as TWO SEPARATE TICKETS. If you would happen to miss your first flight or if your first flight is seriously delayed and you miss your connection, then as far as the second flight is concerned, you are a flight NO SHOW. The first airline only has an obligation to get you to your final destination with THEM, even if it happens to be three hours late. The second airline has NO idea that you are connecting to a flight on another airline. If you are a no show, again, they owe you NOTHING. There's the rub.
