We were cold in our seats on our flight to Seattle.The flight attendants were understanding and were able to move us to seats where we were more comfortable. Out request came as they were busy distributing food and drink but they did not show any tension at our poor timing. I was very impressed by this and their kindness. Both of our flights had caring and patient attendants. One attendant, Victoria, on our flight from Zurich,very patiently calmed an irate passenger down so that soon this person was smiling. Thank you.
