Pros: Flight attendant was very fun. It was her birthday and made the day fun for everyone.

Pros: Crew and gate staff very helpful (see below).
Cons: I needed wheelchair assist at both ends. In each case I was waiting over 30 min. At the departure end there was a danger of missing the flight so one of the gate staff wheeled me, Amina was amazing. Another long wait at SFO. I spent almost as much time waiting for wheelchairs as I did on the flight!

Pros: Full flight, we got on smoothly and took off on time. The plane was clean and the pilots during abbouncekents were easy to understand and funny.
Cons: I had to wait over 1.5 hours to use the bathroom because of the food and drink carts. The flight attendant would not let me use first clsss and told me I had to wait. That was way to long to make someone wait.
