On most airlines, if you live in the city from which the flight is departing, you will not be eligible for compensation. To avoid the hassle of dealing with a flight cancellation (or delay), try booking flights that depart early in the day. That way, if your flight is cancelled, you will have more options for being rebooked on a later flight.

Certain FTP servers support both active and passive transfers while other FTP servers only allow active transfers.
