Priced out what's probably the same fare on the Virgin website and got this message:
2 adults USD 378.00 each
Total taxes, fees, charges and surcharges. This includes the September 11th Security Fee of $2.50 per segment, and carrier imposed fuel and insurance surcharges. USD 434.46
Total USD 1,190.46
Please note that this fare does not qualify to earn Flying Club miles or tier points.
Still sounds like a great deal and I'd definitely consider taking it anyway, but all those just out there for the miles folks may want to think twice.
