That’s because MasterCard Worldwide and Yapta.com airfare tracker have partnered to introduce the MasterCard “PriceAssure” airfare price assurance program. The new solution tracks flight itineraries and offers customer service to help secure airline credit for savings on future travel and if the same itinerary theyâve purchased with their enrolled MasterCard card later becomes available from that airline at a lower price, minus any airline change fees. The “PriceAssure” solution was designed to help you save money when booking air travel at a time when most consumers are feeling frustrated and overwhelmed during their search for low-cost flights.
