Cheapest way to get from Stockholm to ARN airport?
Sorry for the dumb question, but I've googled this question and came to a bunch of answers for getting FROM ARN TO Stockholm. I'm looking to confirm if this is true for the opposite way:
I will arrive in Stockholm via ferry. I will be buying a 72hr SL pass for ~$230SEK. The question is: Can I use this SL pass (within the validity period) to get from Stockholm to ARN airport (probably via Märsta station + Bus 583) without any additional surcharge? If not, how much is the surcharge, and how do I pay it? (I plan to do this to catch a 11am flight this saturday)
Similarly, I believe I can just buy another SL 24/72 hr pass when I come back to ARN and get in the city via bus 583 + train without additional surcharge? Is there a machine or office to buy this pass at the airport?
