......for me, MEM has always been the laid-back no-stress DL connection point.....a 30-min connection is not a worry there, unlike a 45 min connection at ATL or DTW, which gets me fidgety
While the short connection times in MEM make for overall faster travel times to/from OKC......the short connection time in MEM means less chance for BBQ ingestion or SkyClub lounging!
