The plane was not full. I had a broken toe, newly injured, and I was able to elevate my leg on the middle seat as per doctor’s orders. How could I have done this if the flight was full?

I was surprised in that although having C30 & C31 boarding passes, I still could find 2 seats together and we didn’t even have to check in our carryons which is what I was expecting.
