I bought tickets for my wife and I and then a few days later added tickets for our 3 kids. I had to link us to their tickets in order to buy them. When I looked up the reservation number for online checkin their names do not appear on our reservation. I never got a separate email with their reservation information and didnt think I needed anything because it said it was linked when I bought them. What should I do to find their reservation information? Will the check in people just see them on there and print boarding passes for them?    Thanks for your help! ... View more
