Your boarding pass is the easiest way to access all of the necessary details for a certain Op. With the boarding pass, you are able to view directions to the site, the date and time of the Op, your point of contact's name and phone number, and the rally point (where you need to go to check in). It is best to have this pulled up as you are walking into the Op in case you need to quickly check any details.
To access this information, click your dashboard (this is where you app will usually land when you open the app) -> Schedule -> then select the Op you need the information for.
