I will soon be flying from MAN to HKG via DOH and the DOH-HKG flight provides a Comfort+ seats option in Economy Class. I tried to search online about the seats, but the only thing I knew is that those seats are probably similar to Premium Economy of other airlines.

Is there anyone who has experience with it and can share the difference between Comfort+ seats and standard/preferred seats? E.g. Seats/legroom, meals, services etc.
