natiaonal express return的票可以改时间吗

印象中是不可以改的，如果要改，需要额外付改票费（和差价）。 看了下 是这么说的：About your ticket: Please note your ticket is valid for the date and time specified on your ticket. Amendable tickets require changing prior to departure time and will be subject to an administration fee and upgrade to the current price of the new journey. Open return tickets must also be validated in advance of travel.  订票的时候 你要看仔细咯。
