Hi there,
As far as I know, the points system only applies to your initial training course. When you're late for your report time, the best thing to do is to phone the ops desk and let them know what's happening. Then, when you get your crewlink message about being late, go to your pm and tell them what happened. If traffic is bad due to accidents, the company will know about it, as other crew will be late too. You can't be sacked for being late a couple of times. You may be called for a chat with your pm to find out why you were late, and it could possibly delay your wings course. Don't worry too much about it though, just concentrate on getting your assessments done and don't forget to book the pre-wings meeting with your pm. They're very "busy" at the moment, so the sooner you book the better.
