Earlier this year, FedEx outlined the importance of air cargo routes between the United States and Cuba in submitted documents to the U.S. Department of Transportation. As part of America’s expanding relationship with Cuba, DOT recently asked for carriers to propose flights in and out of cities on the island nation. When a final list of approved domestic carriers was released, it became obvious that FedEx’s pleas fell on deaf ears. In early July, DOT proposed that Delta, American and United receive the all-clear to start flights into Havana later this year. Southwest, Alaska, JetBlue, Frontier and Spirit Airlines also received tentative approval to begin routing to the island nation. In all, 12 airlines submitted applications for 60 daily flights to Havana. DOT has only made 20 spots available each day.
