It seems the CAI - HNL fare is back. It's a little more expensive now, coming in at £1,398. Thats 8*140 = 1,120 TP or £1.25/TP. No idea if it's possible to get F on the transcons this time, but a pretty good fare. Rakes in a decent number of avios too, considering the sheer distance involved. Seems that stopovers are permitted too. You can find it same way as before, find the rough date in Google flights then use matrix to force a routing visa LHR, JFK and LAX..
