Did R’ Moshe pasken one MUST sit next to a woman?
Did he pasken one is allowed no matter how she is dressed, and no matter how he feels he will be affected by it?
Does nobody disagree with R’ Moshe, and is someone not entitled to follow his own posek?
DY: Alecha L’Havei Rayah that there is some legitimate Psak (not by Rabbi Saul Lieberman or other reform Rabbi) that there is some sort of issue. Then we can discuss parameters of such a P’sak, whether it applies to men as well as women (B’shittas Gur), and if one does hold as such, would they be Mechuyav L’chatchila to purchase two seats instead of relying on the B’dieved of moving others around and possibly being Over if no one is willing to move.
P.S. If the issue is that of dress (and they hold it is therefore Assur to sit next to such a woman), I don’t see how one can remain on the plane (since they will still see her) even if they don’t sit next to the woman, as it is B’geder Ikah Darcha Achrina (they can take another flight or pay for the front seat in first class).
That all being said, we are (in general) Machmir on Arayos. If it is a legitimate issue, I fully expect people to start coming from EY collecting so that those who come collecting from EY should be able to purchase an additional seat.
