In the run up to Feb. 14, agricultural specialists at Miami International Airport have processed about 940 million stems of cut flowers, according to U.S. Customs and Border Protection. Around 90% of the fresh cut flowers being sold for Valentine’s Day in the United States come through Miami, while the other 10% pass through Los Angeles.

Thousands of airport workers play a pivotal role in whether romantics across the United States enjoy the next few days. The country’s top two sources of fresh-cut flowers are Colombia and Ecuador. MIA receives 91% of all flowers that are imported by air.

Miami International Airport is projecting a record-setting flower haul this Valentine's season, with an estimated 1,500 tons of cut flowers coming through every day between Jan. 1 and the end of February.
