The Duke and Duchess of Sussex have been facing some backlash after it was revealed they took a private jet to Ibiza, Spain, for her 38th birthday.
Prince Harry and Meghan Meghan took their three-month-old son Archie on a private jet to the island of Ibiza for a six-day break earlier this month and it has been claimed that the return trip totalled £20,000 (NZ$37,838).
According to flight logs obtained by MailOnline, the pair are believed to have flown from Farnborough Airport in Hampshire on a Gulfstream 200 and returned on a nine-seater Cessna 500 XL, owned by NetJets, which has been dubbed "Uber for billionaires".
While the royal duo had a reputation for being "eco-warriors", they have since been labelled as hypocrites for not considering their carbon footprint with the environmentally-damaging flight.
Former royal protection officer, Ken Wharfe - who protected Princess Diana and her sons Prince William and Harry in the '90s - called the Duke and Duchess of Sussex out for having a double standard when it comes to the environment.
"Frankly it is hypocritical," Wharfe told Vanity Fair.
"Harry can’t be preaching about the catastrophic effects of climate change whilst jetting around the world on a private plane."
"Why put another plane in the air when you could go commercial," he continued.
"During my time at the palace, most of the flights we took were commercial on British Airways, the national carrier.
"We always flew commercial; in fact, I don’t remember flying private. It’s no guarantee that security is any better. You’re better off with BA security because they’re used to working with VIPs."
The revelation comes after Harry previously urged the public to "take action" to lower their carbon footprint.
Speaking in March, he said: "Climate change is a humanitarian issue not a political one, and one where we've been far too slow in waking up to the issues and acting on the damaging impact our ways of living are having on the world.
"We now have the facts, the science, the technology and the ability to save not just our planet but ourselves. You don't just sit back and wait for solutions, you take action and create them."
It is not known who paid for the trip as it is possible they may have borrowed a jet from a friend whose plane is managed by a hire company.
The trio are believed to have flown to Ibiza to belatedly celebrate the former actress' 38th birthday, which occurred on August 4.
According to reports, the couple stayed in a secluded villa on their break and not only did they travel with their own security team, but they also hired five local escorts who knew the area.
Meghan previously holidayed on the island with a group of friends including Misha Nonoo - who is reported to have introduced her to Prince Harry - back in 2016.
As for Archie, while the brief break to Ibiza was his first time overseas, the tot will be getting on a plane again before the year is out as he'll be accompanying his parents on their official visit to South Africa this autumn.
Meghan and Harry, 34, admitted in June they are "really looking forward" to the trip.
A post on their official Instagram account read: "The Duke and Duchess are really looking forward to meeting so many of you on the ground and continuing to raise awareness of the high impact work local communities are doing across the commonwealth and beyond. This will be their first official tour as a family!"
