Pros: The crew saw I was travelling with my young son; baby and elderly parents. We were placed at the front of the crew and were kind enough to allow me to board first.

Cons: Most passengers had to put cabin bags into the hold. These were taken at the gate, it would have been nicer to have had this notified by text or when checking in so the bags could have been left at the check in desk.

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.
