It’s the ultimate game of hide and seek for travelers in the Phoenix-area! Ultra-low fare carrier Frontier Airlines (NASDAQ: ULCC) launched its “#DiscoverDiscountDen Giveaway” today, hiding five Frontier-branded piggy banks throughout Downtown Phoenix containing free flights for the whole family ahead of the holiday travel season. Team Frontier has been busy placing the banks in creative spots across Phoenix’s city center, and consumers can look to the airline’s social media channels for clues on where to find them and how to claim the prizes inside.
