I was flying from SAN to DEN yesterday and suddenly became ill. (Of course, it couldn't have been the salad with mystery meat that made me sick.) The flight attendants were wonderful and gave me whatever I needed; cold towel, ginger ale, club soda.
I plan to write United a letter and will provide the name of the flight attendant that helped me the most. She had 36 years on the job. 36 years and still had a great attitude.
By the way, the restroom had a plethora of "air sickness" bags.
