Delta is getting married to Northwest airlines--forming the May-December romance of the airline industry--and will bring as its dowry a fleet mostly of Boeings and Bombardiers. Like Northwest, however, the oldest part of Delta's fleet are McDonnell-Douglases. At the end of the year, Delta had 117 MD-88s still operating at an average age of 17.5.
