In one line
Port hours bill continuously while the port is provisioned, then per GB on the way out.
What gets missed
Data transfer in is free, which makes the link look cheap, but port hours run around the clock regardless of traffic. The colo cross-connect comes from your provider, not AWS, and SiteLink adds its own hourly fee.
