Present simple and present continuous to talk about the future

We can use both the present simple and the present continuous to talk about the future. We usually use the present continuous for things we have planned and that we are fairly certain will happen. I'm meeting Julia later. She is arriving this afternoon. We usually use the present simple for future timetables from some kind of business or organisation. It might be a train, bus or plane timetable, or a school or event timetable. It's usually not something that you can change. The class starts at nine. Our plane leaves tonight. ​Let's review!
