Any Way You Slice It, It is Still a Lime
Delta Air Lines used to cut the limes served with drinks on its flights into 10 slices. Northwest airlines used to cut its limes into 16 slices. Despite a potential savings of up to $500,000.00 per year, Delta Air Lines opted to keep cutting its limes into 10 slices, but because it apparently loaded more limes onto its flights than needed, Delta Air Lines now carries fewer limes on its flights.
The lime scenario is only one of many different issues, problems and items to be resolved in The Minutiae of an Airline Merger.
