however, will be flying PS for the first time ATL-FRA in a few months. My wife and I usually fly D1 but just cannot justify the inflated prices presently.

On the A332 I notice for D1 the lavatories are both by the flight deck and it appears the closest lav for PS is back by row 37 in economy.

Are PS passengers allowed to use the D1 lav or are they required to use the ones towards the back?

Thanks
