Although the aviation industry is growing year on year, profits for Rex are declining. Rex has an aging fleet of turbo-prop aircraft which service regional destinations with heated competition. The Saab 340 primarily operates in and out of East coast destinations. Aircraft manufacturers are developing smaller more efficient jet aircraft with this market in mind. Unfortunately it appears that a company like Rex won't have much of a future in the next generation air traffic network.
