Depends on carriers and routes. If you're asking about the US carriers there's not much difference between C/F services. Obviously there is a cost difference but it's all route specific. If you are flying on an Asian carrier (SQ/NH) there is a pretty big difference between C/F. Maybe you could provide us with more details and we can provide more answers.
