So CGK is losing JAL Suite for ~6 months. They have been downgraded to Solo and Shell Flat at the beginning of this year for a month already.
Regular downgrade of 1-2 months is usual but this is the first time I saw it happens for 6 months. Could it be they are doing some fleet upgrade on the 773? Seat, IFE, wi-fi, etc? Of course this could simply be nothing more than major maintenance of couple of their 773s are due
