No airlines have hubs at MSY. Southwest has by far the largest operation, with 58 flights a day, including nonstops to LAX, LAS, PHX, and SAN in the West. CO has 18 flights a day including 757 service to IAH, and DL has like 20 (also 4 comair's) mainline jets including 767's to ATL. So no hub, but we have decent service. Internationally, not much. We have a daily AC 737 to YYZ, a 4x weekly Lacsa 737 to CUN, and a 5x weekly Taca 737 to SAP. Plus scheduled twice-weekly charters to MBJ and CUN.
