we were on the jade from athens april 8th thru the 17th. ncl required a negative covid result 3 days before sailing, so we had that done. at the pier in athens, before being allowed to board, we were tested once again (no charge) the 1st day was a sea day and the 1st port on the 10th was jerusalem. on the sea day (april 9th) the israeli health ministry sent their own inspectors, and the entire ship was tested once again. all the results had to come back before we were allowed to disembark in israel.
all that being said, i didnt hear of any problems. or cases of covid on this cruise.
i will give ncl credit where it's due. they seemed to have all their based covered as far as safety of the passengers and crew were concerned.
now, obviously this may not be the case for all ports of call and all ncl ships, but we had no problems at all.
to even simplify things, we flew delta and needed another negative covid test before we were allowed to board any flights back to the u.s. we stayed at the athens marriott, and right next door was a hospital. it took 30minutes to get t he test and results, no charge, and the next day we were happily on our way home
