What time does rush hour begin on a weekday please? I have to travel from the Hbf to the airport for a flight with check-in closing at 10 a.m. I only have a carry-on, but it's still luggage which could inconvenience other commuters. So if I were to plan to leave at 7.30 is that early enough to miss the beginning of the rush hour or not?
Also, what would be the destination to put in on the ticket machine please? Flughafen?
