It still says 777 in MMB but my boarding pass says world traveller plus seat 12G and there are no configurations of the 777 (per basource) that have a row 12 in WT+ except for the version that has no F but there is definitely F on this flight. That's why I was hoping to find out exactly which plane it was going to be so I could check. I suppose I will just have to be patient for now!
Is this a paper boarding pass or your mobile.
I was upgraded a couple of weeks ago from WT+ to CW and my mobile still said WT+ with the CW seat number.
