We're down to just two questions left for the DTW quiz. We still need the last two cities Eastern served from DTW. One is so obvious that all of you will cringe when you realize you overlooked it.

Also, my questions mentioned every airline that served DTW, except for one. The airline that hasn't been included in trivia questions so far served DTW with three flights a day, to two cities, using one type of jet aircraft. Which airline is missing, what cities did they serve, and what equipment did they use?
