Looking at the timetable, and saw that only one mainline (OC9) (and the only one to CHI) is during the MEM-ORD route, which suxs. Ever time I flown this route they are usually pretty full. Is it because MEM now fly to MDW. Where the 319 and the other DC9 went to? I hope one day that the mainline will return for all the flights to MEM-ORD, and add one to the MEM-MDW
