While I have to say that this update is a big leap forward in the game, for which I'm grateful to the team, I also have to say that it has a few glitches. I agree with the point made in the thread, having a fleet of 763s I had found this issue too.
I was trying to configure my planes with a new layout with more or less the same capacity of the current one. If I understood correctly Comfort should correspond to the old Eco Plus, which I had used on my long haul planes, while Comfort Plus seats should, more or less, correspond to a Premium Economy. Honestly speaking I think that those seats are a bit too wide.
I cannot arrange a 2-3-2 layout in Economy Class, which is the one that most real 763 operators have with a width varying between 17 and 18 inches, exception made for some charter operators which have a sardine can configuration of 2-4-2. The only economy seat that allows You to get a 2-3-2 is the Leisure/Leisure Plus which is not the ideal one for long haul flights, With Comfort seats You get 30 (which, by the way, corresponds to the missing row of seats) less connecting pax .
Let's do some simple accountancy, and I'll take my case as example: with a fleet of 20 763s it's 1200 pax less each day, or 438.000 pax less each year. On the monetary side of the thing, let's put an average fare of 500 AS$, it turns out that we'll loose 219 million AS$ less each year, it's a sum that could never be offset by the increased business class fares.
That's a huge number, and keep in mind that I'm a small widebody operator, but those who have a big wb fleet are going to be even more negatively affected by this. After a few tests, Airbus widebodies suffer from the same issue, since they should have an economy layout of 2-4-2 whereas they get a 2-3-2 with Comfort and a 2-2-2 with Comfort Plus.
Long haul operations were already negatively affected by the fact that a good portion of those long range routes could have been operated more profitably by a flock of 739HGWs, and while the new seating system is a huge advance in shorthaul, it's going to make long haul flights even more unattractive.
