Ups and fedex had trouble in the start up lots of money to fork out in planes , hubs ,transports
Eventually the both started making money.
DHL came at the wrong time when jet fuel and cost of transport was at its all time high.
Hoping to recover in better times earlier operation cost but it was ether go under or drop your biggest liability ( domestic service )
and focus on international service ( imports from china and textiles from europe )the biggest money maker.
