Flight
State College has one small airport for 'puddle jumper' planes. Only a select few airlines service it a few times a day. They are typically smaller jets connecting through a larger city so check times for layovers to make sure it's same day! Also means smaller plane (3 seats across) so it is not really roomy.
Flight
Harrisburg, PA is approximately 1.75 hours away and is the closest international airport in the area. You will still have to drive from there to get to State College, PA.
Flight
Pittsburgh is the closest other major airport and is approximately 3 hours away from State College. You will have to rent a vehicle to get into town but the drive is beautiful through Appalachia!
Flight
Philly is approximately 3.25 hours away from State College. You will have to rent a car from there or take a train to Huntingdon via Amtrak if you want to take the scenic route. :) And let me know if you need a ride from Huntingdon. :) (schedule accordingly)
House Or Rental
There are plenty of options to stay with a large group but you have to coordinate on your own!
