I plugged in the same dates as vacationfinatic and got the same rates they did for a minivan, also using no codes (southwest)...When I tried to extend it out though, it would not let me book past June 7. I think like their airline, they open up booking for 4 or 5 months. By clicking on the calendar for your book dates, it will show you how far in advance you can book. I would keep an eye on that, and then try again when your dates at the end of June open up...Don't give up hope yet, you may be just trying too early for their site. Which doesn't do me much good either since I need dates in early December!
