Newark flights aren’t a problem . Meisim fly from jfk
Pretty much any direct flight is a problem out of NY, Elal does have a flight where they say they don't take dead people
your best bet would be flying with a stopover ur 99% that they wont pick anyone up on the 2nd leg,
except if the connection is a big city in EU and you flying with Elal, because than your'e 99% sure that they mind have an Aron .. bottom line, connection but not with Elal
I don't think its 99% but your right u gotta be careful.
Don't they have a separate compartment to make it's own Ohel.
