This particular Delta Air Lines flight may not have met your expectations in terms of the food served on board. It appears that the portions were smaller than anticipated and the side dishes were minimal- no salad, no bread rolls, no fruits. Perhaps there are ways in which the airline could improve the dining experience for their passengers. Why can't Delta offer better customer service when other non American airlines are able to do it?
