Best if used by...?

    Q. If you have a voucher from an airline and it has to be used within a year of issue does that mean that the flight has to be booked within one year of issue and you can fly after the date; or does it mean that you have to use and fly within the time period?  

    A. In most cases, it means that all travel must be completed within one year of the voucher’s issue.
