I have not, but spoken with them several times. We are limited to 2 checked bags- one 50 lbs, 1 25lbs. The carry on is tricky. It can be 22 lbs, but the dimensions are much smaller than standard carry on size: 17x 13.5x 9.5. The complementary Seabourn tote is too large ( longer than 17”). When I queried them in what would happen if we were over the limit, the answer, after quite a long hold, was they really didn’t know. It was suggested that your bag may be placed on another flight or perhaps it would be shipped to your home at your expensive.
I have no idea how strict they are, I posted the question on CC and haven’t gotten a response.
We have 3 nights in Santiago and 3 in Buenos Aires/ Iguazu so we are packing for everything. 😳
Hope this helps!
