1. OLCI your group anytime 24 hours or less to the departure time of your flight.
2. When you get to the stage where it asks you to print the boarding pass you don't need to, you are checked in.
3. When you get to the airport you and the other travellers in the party will need to show identification and you will then be printed out your boarding passes which will be the same seats as you selected when you checked in online. (unless of course you have been upgraded or something like that)
That's it. You don't need to do anything else.
