I booked a flight (not at ac.com) and selected 17F, which implies the intended aircraft must be the 25J/188Y version, since this seat doesn't exist on any of the others.

Any words of wisdom about this particular aircraft? Sadly a J seat is not an option for this particular flight, so I'd be more interested in learning if 17F is actually a lavatory, doesn't recline, has spikes in it, or is reserved for lunatics only
