[QUOTE= Which brings up a good question...ARE they the same redemption? 50 minutes is too tight in my book to risk it.[/QUOTE]

Yes, that CX710 and CX884 was what the redemption system came up with when I searched for a SIN-LAX. The CX882 was not available at the time of booking but now is - and it's because the photos from a F review I read didn't seem to show F being that much better that I'm considering saving on the points difference between F and J. But your and others' responses above are very helpful I'm now considering sticking with CX884.
