I've just booked flights for a colleague in early May, and the CDG-DEL sector is scheduled on a 772. The seatmap shows several Economy Comfort seats:




Looks like rows 19 to 21 will all have Economy Comfort, and then rows 35 to 36 as well. The middle four of rows 37 and 38 are also being sold as economy comfort, but not the A-C or J-L seats. I wonder if the tapering of the aircraft and duo seats made it harder to put the same number on the two sides of the aisles.

In any case, my colleague will probably end up taking a flight via AMS instead due to a change in schedule, otherwise I'd have reported what the experience was actually like.
