米蘭機場快線線上購票求助!!! - 自助旅行

請教一下板上大大

現在米蘭機場快線有推出 線上購買來回票20歐的優惠

但是小弟不才 搞不懂他的意思

這個來回票是線上購買後 三小時內就得啟用嗎???

Please remember that the ticket for the outward journey, like for all tickets
purchased online, must be used within 3 hours from the time of purchase. The
return date - which may be no later than 30 days after the outward journey -
can be changed online up to one day before your planned return
