I'd be glad to have your help . Could you make the air-conditioner cooler ?
neutral
assistant
I'm sorry . We can not regulate the air-conditioner . As soon as the plane takes off we'll be able to get better ventilation , and the temperature here will drop . Let me get a wet towel for you at the moment .
