Before the date was extended to 2024, we thought this would apply to us for our Prima cruise form London (Southampton) to Iceland including the Netherlands, Belgium (which has now been cancelled due to low tides), and Norway. I called our TA and he thought it would be taken care of with the airfare as that its how it is presently done with Australia.. I then noted we would be flying to the UK which is not part of the EU. He said he'd have to think about that.
