Is there any advantage to this? I understand doing on-line check in allows them to print up your stuff ahead of time so theoretically you get through check in faster. We have done it on our prior trips. But I can't understand why there is any benefit (to them or us) of doing it more than a week ahead of time. It not like they are going to put your packet together and leave it sitting behind the counter for 2 months. Does anyone know the logic in this?
