It was poor. Eva air seated me in a different row than my autistic daughter. It was stressful for her and she spend a good portion of the flight asking me the same questions for a 12 hour flight for reassurance. I spent the 12 hour flight looking behind me seeing if she was ok. Meanwhile there was an empty seat in the row behind her. It was the worst flight I've ever had
