I wondered how this worked.
Grok says
International Air Transport: The Holy Fire is transported to Orthodox countries via specially arranged flights. At Tel Aviv’s Ben Gurion Airport, planes from nations like Greece, Cyprus, Russia, Georgia, Ukraine, Serbia, Bulgaria, Romania, and others await to carry the flame. The lanterns are designed to safely transport the open flame in pressurized airplane cabins. For example:
In Greece, the flame is received by church and state officials, then distributed to cities like Athens, Thessaloniki, and Ioannina via additional flights or ground transport.
In Russia, the flame arrives at Moscow’s Christ the Savior Cathedral with presidential honors and is distributed across parishes.
