We fly from Syracuse, NY (and sometimes Buffalo).
Last August, our flights on Jetblue were $290 pp return (non-stop flights) from Syracuse.
This year, same time period, flights were $330 pp return (again, non-stop each way via Jetblue). We purchased for both trips in January of the same year. Current prices for the same flights we have for August 2013 have increased to $460 pp, round trip.
Our Christmas flights were $375 pp, round trip, non-stop from Buffalo. One way via Airtran, home via Jetblue. This price included seat selection and baggage costs with Airtran.
When the SW and AT schedules were first released for the end of August for flights from Buffalo, we did see one-way non-stops around $125 pp.
