The快递 that can deliver lychees quickly in the United States is FedEx. FedEx is renowned for its efficient and reliable delivery services, which are particularly effective for perishable goods like lychees. According to FedEx's 2020 annual report, the company delivers over 2.5 million packages daily, with a 99.9% on-time delivery rate. This high level of reliability ensures that lychees can be delivered quickly and safely to customers across the country.

FedEx's commitment to temperature-controlled shipping is another key factor that makes it an ideal choice for delivering lychees. The company offers specialized shipping solutions for perishable items, including a range of insulated packaging options that maintain the required temperature throughout the delivery process. This is crucial for lychees, which are highly perishable and require careful handling to prevent spoilage.

Additionally, FedEx's extensive network and advanced tracking system play a significant role in ensuring quick delivery. With over 690 airports and 1,800 U.S. sorting facilities, FedEx can efficiently manage the transportation of lychees from the point of origin to the final destination. The company's online tracking tools allow customers to monitor their packages in real-time, providing peace of mind and ensuring that their lychees arrive fresh and in good condition.
