Depends on WHEN. Cheapest days to fly are Tuesdays and Wednesdays, and there are always new deals even up to the day before your plane leaves. I've seen these flights go for anywhere from $100 to $500! Do you research, testing different dates for the cheapest results on www.expedia.com or www.orbitz.com. I would go with Expedia, because the prices shown are a TOTAL...including all taxes and fees. Other sites will tack on an extra $50 or so on top of the price listed... and this can be pretty misleading. Good luck! :)

I'd suggest going to www.expedia.com or you could try yahoo travel. There are so many variables, time of day, day of week etc, it's much to hard to say. Good Luck
