There is a direct bus from the airport (Flybussen) that leaves at 10 minutes past the hour, approximately every hour (every two hours on Saturday) and takes about 55 minutes. This is bus F11 to Fredrikstad, leaving in front of the arrival hall. You will get out at the first stop Korsegården. Ask the bus driver to order a taxi from Korsegården busstop to Ås/NMBU. Alternatively, it is an easy 20 minute walk from Korsegården to NMBU.
Oslo Airport to Oslo
The airport express train (Flytoget) from Oslo Airport to Oslo S leaves every 10 minutes, and takes ca 20 minutes. Tickets can be bought at the machines, or you can swipe a credit card at the gate. Note: these tickets will only get you to Oslo S; you must buy a separate ticket Oslo to Ås.
Alternatively, there are local trains from the airport to Oslo: the R11 (towards Skien/Larvik), L12 (towards Kongsberg) and R10 train (towards Drammen).
