Hi there, I went through a lot of posts here and I couldn't find anything similar to my question. I'm a permanent resident in Canada and I'll be going on vacation (flying) for the first time since i've got my PR card. My question is: flying back to Canada to check-in online with my airline, when they ask about the travel document, do I put my passport information and just present my PR card when I lend in Canada or I need to use my PR card to check-in before the flight back to Canada? I'm not sure how it works with eTA. Will the airline's system know that I don't need eTA when they scan my passport on the way back to Canada? Thanks
