Meghan Markle and Prince Harry were flown around Nigeria for free by an airline with a "wanted fugitive" as its chairman.
Dr Allen Onyema, founder of Nigerian airline Air Peace, provided the Sussexes with free flights during their three-day tour of Nigeria.
However, Dr Onyema is also a wanted man in the US, facing multiple charges linked to millions of dollars worth of alleged fraud, after a federal indictment was filed in November 2019.
Stanley Olisa at Air Peace said the Sussexes were given the "complimentary flights" by the CEO, along with "everything they wanted" because "they are royals".
The indictment accused Dr Onyema of allegedly "using his status as a prominent business leader and airline executive to launder more than $20million from Nigeria through US bank accounts".
There is no suggestion that either Harry or Meghan were aware of Onyema's history before they met him.
Olisa told the Mirror: "The planes were chartered. It was just the royals and their entourage. They were not flying with other passengers.
"We understand that they are royals so we gave them top-tier treatment on board. They were given everything they wanted. It was an exclusive experience. And we flew them back to Abuja in the evening. Everything was complimentary."
He added: "The chairman of Air Peace gave Prince Harry and his wonderful wife Meghan free flights to Lagos and back as part of his contribution to the successful hosting of the couple."
The couple and their entourage flew 664 miles on a 120-seat plane creating around 12 tonnes of carbon emissions.
The average annual carbon footprint for one person per year is about four tonnes.
Like his father King Charles, Prince Harry has also been a vocal champion of environmental causes.
LATEST ROYAL NEWS:
During the visit, the couple visited a local charity and met with military leaders, injured soldiers and schoolchildren.
This comes after it was alleged that King Charles was 'absolutely furious' that the trip had taken place anyway.
Royal author Tom Quinn said: "Everything you might expect from an official royal visit was there – the receptions, the visits to schools and charities, to wounded soldiers and the disabled.
"Meghan and Harry's speeches and their whole attitude has been designed to give the impression that they are still fully paid-up royals and William and his father King Charles don't like it one bit."
GB News has approached Prince Harry, Meghan Markle and Dr Allen Onyema for comment.
