I have a UA award ticket in business class ICN-HND (OZ), HND-SIN (NH), with a 50 minute connect time. Arrives HND 23:00 and departs 23:50. I know this is outside the MCT, but realistically, what are the chances of making it? I won't have any checked bags.

I suppose it depends mainly on the timeliness of the incoming flight. Can anyone advise how I can check the recent on-time performance of a nominated flight? I seem to recall there is a tool out there somewhere.
