   Delta Air Lines is flying two 727-200s with Valsan developed
   winglets.  The list price is $550,000 per aircraft with each winglet
   weighing 45 kg (99 lb).  The fuel consumption savings depends on time
   spent at cruise.  Valsan estimates savings of 4% for short haul
   operations and up to 7-8% for an executive aircraft on a 7-8 hour
