Destination Aiport not allowing T/O's to their Airport because of WX
Can/does ATC in your part of the world denay commercial operators to take off from their departure Airport because - their - Airport which happens to be your destination is below landing WX minimums?
Alternate airport is Cavok so no problem if the WX at Dest. does not change and you have to divert
The point is not because of traffic congestion in their airspace but because actual and forcasted WX shows to be below minimums for arrival at destination.
Q. is also not if it makes any sense or not to T/O with that WX at destination.
