They are indeed all F16 Y120. The reconfiguration of the cabins was completed recently, and all -80s now have the same capacity. The strange thing is the TWA config of F16 Y115 has not been around for some time... it went to the AA
standard F14 Y115 long ago. Definately time to update that page.
The only major difference now, which can still help you tell an ex-TWA bird from the inside is the position of the first class lav. On the ex-TWA birds the lav is just aft of the entry door, with a closet aft of that. The AA
birds have a closet aft of the entry door and the lav is aft of the closet.
