When I boarded the plane, I asked flight attendant Nanci if the flight was full, she said no, but the only available seats were middle seats. I was seated on the aisle with people in each of the other two seats. Later, Nanci came by and checked her pad/device and offered to have me move across the aisle to an empty aisle seat where there was just one person in the window seat, much more comfortable; very gracious of her to take the time and effort. Also, Barb and Debra were very friendly and helpful when serving refreshments. Great flight!
