Yes C/C do listen and will deal with it but they cannot control what happens via on-line check-in systems or failure by check-in agents
This is the core problem in many airlines, especially when using associated allocated seating.
Pax can book a ticket and choose to sit at the (over-wing) emergency exit rows.
Pax can book and choose all adult tickets, as sometimes no financial gain is to be made from a child ticket anyway, saving you time and effort during booking process.
The seat allocation process cannot then verify the age of occupants in the emergency exit row, pax are happy for extra legroom booked (and sometimes paid for).
Gate staff check boarding passes for valid flight, not ages in rows of emergency exits (repeatedly heard gate staff say to pax seating issues will be sorted by cabin crew on board, even though at gate there is plenty of time vs in aircraft limited time before departure).
Cabin crew are now faced with a situation they have to rectify, but with pax having paid extra for the bit more legroom are thus hesitant to leave their allocated premium paid seats and will revolt.
Start by changing the IT issue in the beginning of the sequence and problem solved!
