What is an OPEN ticket?

A round-trip ticket with an unspecified return date is considered an OPEN ticket, and the return flight will be marked with the word "OPEN." After determining the date while abroad, the passenger should go to the airline to attach a revised date slip. If a passenger wishes to purchase this type of ticket, they should inform Manggo.net in advance and inquire whether the ticket allows for free date changes, as most discounted tickets do not permit an OPEN return, and revising the date often incurs a fee.
