Our connecting flight was from Newarl NJ to Cabo San Lucas and. it was the most crowded plane I have ever been on. That obviously cannot be helped, however as this was a longer flight I understand that folks legs were cramped, but there were passengers walking around the plane for most of the time. Several times I had a rear end practically sitting in my chair with me as people were standing around just to stand around. Several times our group complained that this was uncomfortable and could they please ask people to sit unless they are using the restroom. Clearly this did not happen. Also for the second year in a row, my luggage did not make it to Mexico. They took it off because the plane was too heavy. We arrived on Saturday afternoon and I did not receive my luggage until Sunday night. Not the way I wanted to start my vacation.
