We are set to fly from Florida to Vancouver on Thursday. we will leave on Saturday on the Koningsdam. All along I thought I read that a Covid test was not needed to fly to Vancouver from the US. We plan to get Covid tested in Vancouver for the cruise. I got something today from Delta that made it look like we do need a Covid test to board plane for Vancouver. Is that correct? I’m driving myself crazy to find out. We do have a layover in Los Angeles. Help!

This is our first Alaska trip. We are flying to Vancouver from Florida early on Thursday morning and board the ship on Saturday. Can we do the pcr testing in Florida on Wednesday for the cruise? I read 3 days so I wasn’t sure if that is Wednesday or Thursday. If we have to wait, where could we get it done in Vancouver? We are staying near airport and won’t have a car. Thank you for your help.
