The Y Class capacity of a 727-200 is 189 passengers.
With the 2 seats they removed near the overwing exits, remained 187 seats.
That is as high a configuration I have flown with the 727...
They all reclined at the same time, or bruised their noses.

For info, the shorter 727-100 was certificated for 131 passengers.
I remember flying some with 129 very unhappy tourists.
The less they paid, the more they bitched (especially if from New Joyzee).
Happy contrails
