So I sound like my grandparents probably by even asking this, but what is the advantage to online check-in? We fly tomorrow out of O'Hare and I just got the email saying that I could check-in online. We're playing to do curbside check-in for our bags, so not having to stand in the line inside the terminal isn't an advantage. I'm just curious to hear if there is any other reasons that I'm not aware of.
