I don’t know – a group of us asked our Rav (in my former city) about davening on a plane, and he quite pointedly said one should daven in his seat. Before you all jump on my with “But Rav Sscheinberg said . . .” I simply feel that I asked for a p’sak from a Rav that I know, who knows me, and is well respected in the city. This was his answer, which I follow.
