Delta has joined the niche marketing game. The airline has a new “contest” going, where viewers can watch 5 videos and obtain Delta frequent flyer points by voting for their favorites. The niche marketing comes in with the selection of the travelers that Delta chose to feature. There is the gay couple, the elderly couple, the black couple, the young couple, and the too-cool brothers. But despite several attempts, our log-in to vote failed, after sitting through all 5 annoying presentations. Nice try Delta – maybe next time just give us better air service.
