From which track(spor) leaves train from central station (Kobenhavn H) to copenhagen airport??
Mostly 5+6, but look at the information boards in the hall when there.
We were unable to purchase tickets from the machine with credit card so had to go to the office there. Take a number before you enter. The reason we could not purchase at the ticket booth was because they said foreign credit cards are often not accepted. But when we arrived in Copenhagen airport at the beginning of trip there was no issue.
Oh ok thanks. I am going to purchase 24-hours CityPass via internet / sms
