One connection reaches almost everything. The Gulf carriers fly to every significant US gateway and out again to the whole region, which means a consignment collected in Houston, Chicago, Atlanta or Los Angeles can be in Dubai, Doha, Riyadh or Kuwait with a single change and a single carrier's baggage policy. On a hand carry that matters more than raw flying time, because every additional connection is another point at which the item and the courier can become separated.
The second advantage is the shape of the working week and the day. The eastbound departures from the United States leave in the evening and arrive in the Gulf around dawn, which puts the consignment in front of a consignee at the start of a working day rather than the end of one. Where the destination is further, Africa, the subcontinent, the Far East, the same arrival makes an onward morning departure and the courier can continue without the goods ever entering a warehouse.
What differs across the region is entry, and it differs a great deal. Some destinations issue a visa on arrival to a US passport holder, some require one in advance, some require an invitation or a sponsor, and at least one pair of countries will not accept a passport that carries evidence of the other. None of that is difficult if it is checked before a courier is assigned. All of it is expensive if it is discovered at an immigration counter.
