Sixteen would-be vacationers were banned from Carnival Cruises after a massive brawl in the Florida customs line on Monday.

The knock-down, drag-out fight involved more than a dozen people of all genders throwing wild punches, sending stanchions and luggage flying at a customs checkpoint in Miami-Dade County, video on social media shows.

The fracas was between two feuding families, local law enforcement told the Daily Mail.

No arrests were made or charges pressed, but 16 people ended up on Carnival’s no-sail list, the company told the outlet.

“I’m about to skip the line,” one bystander quipped, watching the flurry of bodies and fists.

It was the second big-time brawl in as many months for the cruise line.

Two women were charged in May for assault after getting in a fight aboard a Carnival ship on the way back to Alabama, Fox reported.

Lisa Horace, 51, and Tonya Nelson, 58, began slapping each other around after one accused the other of being in the wrong line, according to court docs viewed by the outlet.

“I’m just sorry that we’re here,” Nelson told the judge during a court appearance.

Carnival Cruises attracts a wide variety of guests with budget-friendly Caribbean cruises, which start at less than $200 per person, according to the company’s web site.
