The Prince of Wales visited the Wales Air Ambulance base in Llanelli to mark Air Ambulance Week.
Prince William, the charity's royal patron, met with emergency workers, volunteers, and supporters of the lifesaving charity during his visit.
Among those who had the chance to meet the prince were two volunteers, Brian Tolley and Anne Evans, who have collectively raised thousands of pounds for the Wales Air Ambulance.
Mr Tolley, 80, from Builth Wells, said: "The prince was very relaxed.
"He looked very comfortable and was brilliant with everybody he met here today.
"I thought the visit went very, very well and I really enjoyed my day."
Ms Evans, from Cardigan, has volunteered for the charity for 17 years and raised more than £140,000 through various events and fundraisers.
She said: "It was absolutely fantastic to meet Prince William.
"He is a wonderful patron for our charity.
"We spoke about how long I’ve been volunteering and he mentioned the fact that a lady jumped out of a plane for charity, who was 102.
"I said my defibrillator won’t let me do that.
"He was really down to earth and I could have talked to him for ages."
The visit coincided with Air Ambulance Week, which highlights the essential service provided by the Wales Air Ambulance and 20 other air ambulance charities across the UK.
The Wales Air Ambulance is consultant-led, delivering hospital-standard treatments to patients and, if necessary, transferring them directly to the most suitable hospital for their condition.
The prince also met with the chief executive of Ascona Group, Darren Briggs.
Ascona has supported the charity in its mission to provide lifesaving medical care to people across Wales.
Mr Briggs said: "It was absolutely fantastic to meet His Royal Highness, he was so down to earth and so engaging.
"It was a once-in-a-lifetime opportunity to meet Prince William, it really was."
Several of the Wales Air Ambulance medics and pilots also had the opportunity to meet the prince.
Critical care practitioner, Josh Easton, said: "It was a pleasure to meet His Royal Highness.
"He had a real understanding and was able to relate to us given his previous work and experience with H1145 and his work with East Anglian Air Ambulance.
"He has a unique perspective and understands what we provide as a service to the patients and the people of Wales."
The prince also took the time to sit down with the emergency workers, as well as chief executive Dr Sue Barnes, chairperson of trustees Kyle Jacques, and director of strategic communications and engagement, Steven Stokes.
Dr Barnes said: "It was a great honour to welcome The Prince of Wales again – the second occasion in just over a year.
"The Prince always conveys an in-depth knowledge and understanding of our organisation.
"His genuine passion for our charity and the people within it is recognised by us all."
Since the announcement of His Royal Highness as Wales Air Ambulance royal patron in February 2023, the charity has seen a significantly positive impact.
This year’s visit followed last year’s engagement where Prince William and Princess Catherine officially opened the charity’s new patient and family room.
