Charters are special flights generated by the system. They are both time limited and quota limited, however those limits apply only before booking. As soon as you book a Charter flight passengers are assigned to your booking and you can fly it at the specified departure time, even if that is after Charter expires!
Remember! You cannot cancel Charter booking. This is to prevent malicious draingage or locking of passengers and cargo. Please make sure that you can follow through on this flight and that all weights (ZFW, MLW, MTOW) are within limits when setting payload for the flight - don't be greedy!
Charter benefits over Free Flights:
Some. While Charters are easy way to make money quickly and visit some otherwise unpopular destinations you cannot cancel already booked Charter flight. This means that if for whatever reason you can't start this flight a penalty will be applied.
Don't worry. Newsky will detect that and NO PENALTY will be applied.
