1) I would like to book a flight with a window seat. 2) Good 3) One passenger became ill (sick) on the plane during the flight. 4) Why do you sleep with your legs sticking out of the blanket.

1) I like my seat to be by a window in a plan. -I really dont get what you here. But I think the correct would be: "I like to seat beside the window." 2) I don't agree with anything you said. -This is kinda correct but it would be concise if you say it in this form: "I dont agree with you." Simple but correct. 3) One passenger got bad in the plan during the flight. -Do you mean got hurt or something? "One passenger was injured during the flight." 4) Why do you sleep with your legs stick out of the blanket. -I'm sorry I dont know how to correct this. I'm not a native speaker so I'm not really sure if this is correct. :)
