Hagoen Harav Chaim Pinchas Scheinberg shlitta said he davens with a minyan on an airplane “all the time.” While strictly speaking it might be permitted to pray at your seat, Rabbi Scheinberg PREFERS that one daven with a MINYAN, but quietly in a way that doesn’t disturb others.
Hagoen Harav Chaim Pinchas Scheinberg is 99 years old. Apparently he is “able to handle standing up in an airborne plane for more than a few minutes.”
