Passport Premiere helps flyers secure international business class travel, often for less than economy. Airlines no longer sell fares lowest to higher.
Fares start high, then move lower (sometimes being slashed by 90%) through business class buying events, and then move higher once they buying event ends.
Examples of fare sales captured by our members can be found at http://passportpremiere.com/graphs/
Passport Premiere is subscription based, but membership costs often pays for itself after the first trip.
