Hello checking in again will not hurt your boarding position if you haven't made any changes to your flight when checking in online it says check in all the time even if you checked in already its weird but it won't hurt your boarding position. You could check in 100 times if you wanted and your boarding position would be the same every time. if you print the pass at home fold it in half as it is easier for the gate agent to scan. You could also use mobile boarding pass if you are on the reservation alone if you don't want to check in again on the website hope this helps blake
