I did some rummaging this morning & got a fairly reasonable cost using a combination of Greyhound & flights (mostly with Delta I think, though I was looking on Orbitz) but I was using Philadelphia, what with not knowing!
I'll have another look & hope Pittsburgh won't be much different.
Penn State is in State Colege, PA which is not particularly close to any major city. Pittsburgh would be closest. There is a smallish airport near the university that is served by smalller airlines from bgger cities but the flights are likely to be $$$.
Look into budget airlines for routes between the other cities--Southwest, JetBlue, Airtran.
Thanks, Attila. I suspect it will be too expensive & he'll have to rethink.
I looked up Penn State & it said it has a lot campuses, but there doesn't seem to be one main one? I don't know if he knows atm where she is exactly. Anyway I'll get some more information from him & see if I can get a rough price.
DS is working at summer camp until mid-August, then he'd like to visit friends at Penn State (where is that exactly?), Atlanta, Austin & San Francisco before returning to NYC for his flight home. He's got about a month altogether.
The separate flights look quite expensive so I was wondering if there's a cheaper way to do it?
