A Cuban stowaway who arrived in the United States inside of a wooden crate will be allowed to stay in the country.

The woman, whose name was not released, was found by a DHL cargo crew inside of a crate the size of a small filing cabinet late Tuesday at Miami International Airport. She did not require medical treatment and immigration spokeswoman Barbara Gonzalez said the traveler, described as being in her early 20s, will be released after standard processing.

Under the United States’ so-called wet-foot, dry-foot policy, Cubans who reach American soil are usually allowed to stay, while those who are picked up at sea are forced to return home.

The woman had herself shipped from the Bahamas to Miami aboard a cargo plane. The 180-mile flight lasted only an hour, so the woman was exposed to freezing cold temperatures, although for a very brief period.

'Certainly she's lucky to be alive,' said Zach Mann, spokesman for Customs and Border Protection.

Federal officials in the U.S. attorney’s office released no information on how the woman got from Cuba to the Bahamas. Yet Mann said the woman’s packaging was done 'apparently with the assistance of others.' A third-party contractor flies the route from the Bahamas to Miami for DHL; the express delivery company was said to be investigating the woman's flight.

Airline stowaways subject themselves to uncomfortable and often dangerous means of reaching their desired destination; however these occurrences are not at all uncommon. In March, a stowaway from the Dominican Republic was sent home after he flew to Miami in the wheel well of an American Airlines jet. A man was also fined $1500 and sentenced to four months of house arrest after shipping himself in a wooden cargo crate from New York to Dallas earlier this year.
