I'm glad you pointed this out, I guess I missed the memo that PL was offering this. But what confuses me is what the difference is with this vs. their normal airfare price product?

With the hotel side, the Express Deals are like Hotwire in that they don't reveal the name of the hotel until you pay. With flights, they appear to reveal all relevant details about the flight - airline, times, stop(s) if applicable. Not sure what I'm missing.
