Depends on what deals you can get, where you live, and where you're trying to go. Driving from Jersey to Breck would have cost much more than flying for me. Gas, food, hotel, and time/effort adds up quick. Could have easily spend $500 driving there and back, not to mention 4k miles on the car. Flight was $300 round trip with bags, got to pick my seat, and free cancellation w/ refund.
