I'm flying on QF27 tomorrow in Y (SYD to SCL) and I noticed that at the front of the cabin is a mini economy section, with Row 40 being invisible but 41 being available to select. The Qantas website reveals row 40 is "unavailable for selection" (see attached image). Does anyone have any experience with these seats - what is this part of the cabin like? Seatguru isn't too informative and recommends simply avoiding Row 41 due to limited recline - will it be quieter however?
