Most flights will arrive at Amsterdam Airport (Schiphol). The easiest way to travel to Delft is by train. Train tickets for domestic travel are available from the yellow ticket machines near the platforms at Schiphol Plaza. Tickets (for domestic and international travel) are also available from the ticket offices, which are situated close to the red/white-checked cube at Schiphol Plaza. Staff at the ticket offices will also be able to provide you with train departure information.
Night train
If you are departing/arriving at night or in the early morning, the NS night network could be the answer. The night trains travel once an hour between Utrecht CS - Amsterdam CS - Schiphol - Leiden CS - Den Haag CS - Delft and Rotterdam CS and vice versa. If it is not possible for you to travel by night train, then why not take a look at the service provided by Schiphol Travel Taxi.
