Yes they do give you discounted prices. She could only quote me a one way ticket there since the 12th is not open for our return yet. She quoted us $142 round trip incl tax on a Saturday afternoon flight but that was to much so she checked a later flight and the price for the later flight was $99 incl tax (much better!). So we put a hold on the reservation and they give you a month to send in your deposit--no cc or cashiers check or mo accepted. When you pay for the flight in full they will take cc. Anyway More of June will open up before our deposit is due so if they have a better rate online roundtrip we will have time to book it. If not I'd be very happy paying $99 each way.
For the best rates be flexible on your flight time and days if you can.
