斯德哥尔摩阿兰达机场来回交通， http://sl.se/en/fares--tickets/
选择有贵的机场快线，普通的机场大巴，和公共交通 583换J36，我想买24h交通卡。请教下：
1）24h交通卡是不能坐机场大巴的吧？
2）用24h交通卡坐公共交通，网站上的这段文字不太能理解，这笔补充费用是坐公共交通需要在交通卡外额外支付的吗？
Travel to and from Arlanda Airport
Tickets suitable for short stays in Stockholm. It is possible to use the regular commuter train service to travel to and from Arlanda, catching the trains between Uppsala an Stockholm.
There is a fee for passing between the trains and the airport terminal at Arlanda. If you have a valid SL ticket, you just pay the passage supplement fee. There is a zone ticket for all three zones with the Arlanda passage supplement fee included.
• ABC zone ticket including passage fee: SEK135 (full price); SEK120 (reduced price)
• Passage supplement fee: SEK85*
* If you are under the age of 18 you don't have to pay the passage fee at all. There is no discount for elderly persons over the age of 65.
我确实想提早预订，因为想买来回票，再加上有个孩子免票，提早预订方便且合算点。
公共交通太复杂要一个半小时才到，加钱是因为你出了市区的圈子，你的24h交通卡只有市区范围，就像巴黎分12345圈，如果你买普通的充值交通卡就是扣50块相当于两次公交的钱
