Of course. It’s past nisht for a GRAND rebbe to fly commercial. Only baby-grands fly commercial. Obviously you’re an apikorus so you wouldn’t understand.
Did R’ Shlomo Zalman Auerback sit on an egged bus? No, he used personal jetpacks. Did R’ Moshe use cars? No, he used Starfleet site-to-site transporters. Do you expect the GRAND rebbe to do anything less than fly a private jet to Miami, IH”K?
