Every Sky Miles member on a Delta flight got a free Virgin Voyages cruise, courtesy of Richard Branson himself

• Delta passengers received a free Virgin Voyages cruise from San Juan on a recent flight.
• Founder Richard Branson appeared at the airport in Atlanta to deliver the surprise.
• The free Caribbean voyage was offered to all adult Sky Miles members aboard the flight.

Delta passengers on a flight from Atlanta to San Juan on February 29 found out they'd be getting a free trip back to the Caribbean destination later this year.

And this time, for a luxury, adults-only cruise on board Virgin Voyages' Resilient Lady — named the best new ship by Cruise Critic's editors in 2023 — a Delta representative told Business Insider in an email.

With a team of Virgin staff members by his side, the cruise line's founder, Richard Branson, showed up at the gate at Hartsfield-Jackson Atlanta International Airport in a red-and-black tailcoat suit over an untucked white button-down and a bold, black top hat — exuding a Willy Wonka vibe.

The Delta representative told BI that the billionaire brought "the vibes" with music, dancers, photo ops, cocktails, and a wheel of prizes to spin for, from Delta gift cards to free Virgin Atlantic flights.

Branson and his team boarded the flight to San Juan and presented all Sky Miles members 18 and older with a complimentary ticket for a 9-day Caribbean voyage in December leaving from San Juan — the ship's inaugural sailing from its new home port, according to the press release.

"The Caribbean has been my home for many years," Branson said. "My excitement clearly couldn't be contained."

Becoming a Sky Miles member is free, according to Delta's website.

The tickets were oversized and as red as Branson's suit — the Virgin brand's signature color.

According to a Virgin Voyages press release obtained by BI, the cruise has a starting rate of $1,120 per person.

A Virgin Voyages cruise is worth the price

Getting a free Virgin Voyages sailing is truly like winning a golden ticket.

I booked a Mediterranean cruise with the award-winning cruise line last summer. The seven-day voyage in a cabin with a balcony cost $5,900. And I thought it was well worth the price.

The ship was stunning inside and out, with modern designs, vibrant colors, and unique works of art. It was jam-packed with activities that made me feel like a kid again — without the presence of children — from an adult playground to jumbo-sized games and dance parties.

Thanks to an inviting staff, a luxurious cabin, and fine dining experiences, I felt like a VIP the whole time.

So, if I got this offer on a flight, I wouldn't sleep on it.
