Just pull a little air in with the pointy end pointing down. Give it a couple gentle flicks. The bubble will rise to the plunger. Keep it pointed while injecting so the bubble stays at the plunger. If you are doing subq you dont have to worry about a air embolism. If you are going into your muscle you still dont have to worry about an air embolism until you get to a couple cc of air.

@iararpg This confirms what I just posted — the COA says 2/3ml under specs. I think 2ml vials are just actually 3ml if you use the entire headspace and fill it to the top.
