Everything was on time and smoothly run. All employees appeared happy and enjoying their job. The delay in take-off was unrelated to anything in Frontier’s control. I wish there were a caffeine-fee, sugar free soda drink option besides water. There are multiple zero sugar caffeine free options.

I will like you ( Frontier Airlines) to fly into LAX instead of ONT because I live in LA and the subway takes me to my house in just 15 minutes
