They were definately enforcing the carry-on rule on my flights. If one didn't have a zone 1 boarding pass and had over sized carry-on's they were pulling them out. They announced it a dozen times before boarding.
We also had people who didn't buy the big front seats who squatted in them! I truly appreciated the patience displayed by the FA's! They have a really hard job!
I really appreciated the overall professionalism of everyone involved.
