Narrative:

We had [the] captain tell us on jetbridge that only one [pack] operating and it would be warm most of flight. It may cool off in air; may not. We had concerns as it was 90 plus outside and plane was hot on boarding. Boarded passengers; and they began complaining how uncomfortable it was. After repeated attempts to ask captain to not go as plane was not cooling off and chillers were written up; he took off. We questioned him again in air saying it was registering 85 plus in the rear of the plane. Passengers hot and crew lightheaded. Captain informed me inflight that we were 60 miles from turning around and going back to [departure airport]. Instead we went all the way to [destination]. Many of us with headaches; no chillers working at this point; all meals compromised. This cannot be ok or legal. What if we had a medical emergency... Crew had to work with lights off as it was too hot to turn them on. Shades were kept down.
