In case this comes up in a future search for someone, I would add one thing for a new flyer - go with a paper boarding pass. The intricacies of downloading the barcode and having it ready to go can add stress to the security process and/or hold up the line. The paper version is straightforward.

x2 for the don't hang out in front of the boarding area until your row/zone is called. Those people who do and block the way for those boarding are called "gate lice".
