Pros: the only thing that stands out was the agent who checked me in at Entebbe. She was pleasant and helpful. Most things were ok, but not special.
Cons: Because I require oxygen onboard, I was not allowed to check in on line. consequently, my wife and I got middle seats that were very tight. At least one of them was an aisle.
