The Lakewood-based Vaad Mishmeres Kohanim today related to TLS that there is no longer a concern for Kohanim flying out of Israel.
“According to Bais Din of Harav Nissim Karelitz Shlita headed by Harav Sariel Rosenberg Shlita, there are no longer any concerns for Kohanim flying out of Ben Gurion airport in Tel Aviv, as all flights on all airlines at every time of the day avoids the cemetery in Cholon,” the Vaad Mishmeres Kohanim said.
