I live near Washington, DC. If I fly to, say, New York, then $500 would be outrageous. I'd expect to pay $100-200 roundtrip for that, depending. It's about an hour's flight.
If I fly to Miami, I'd expect to pay $200-300. That's about two hours.
If I fly to San Francisco, then $500 becomes a reasonable price. That's a six hour flight.
It makes no sense to talk about "a plane ticket" in isolation. From where to where? How far?
