Eat something on the board restaurant. It's way better then in every German train. I will be traveling from Prague to Berlin in sept as well, I use EUrail and bought a pass! but depending on where you are going some require seat reservations which you can purchase 30/60 days before depending on what it says.
You can also take the airport express bus that connects the main train station in Prague with the airport. The travel time is approximately 20 minutes and the tickets cost 44 CZK. Even if it is the bus you can purchase the ticket at the website of Czech railways – Ceske Drahy – as well as at the train tickets counters at Prague train station.
Our tours run regularly so anyone can afford to join the open group tour making it a great travel option for solo and independent travellers. One-way transfer from Berlin to Prague with 3 sightseeing stops. Transport in an air-conditioned minivan. Room for a reasonable amount of luggage.
