Dreamflight has enlisted Myleene Klass as a special guest of honour to join in the send-off of more than 100 specially-selected children going on an incredible holiday.
Myleene met the children going on the Dreamflight charity flight from Heathrow to Orlando in Florida, signing autographs and posing for selfies ahead of the youngsters' 10-day sunshine break.
Gold medallist Paralympians Natasha Baker, David Smith and Sascha Kindred were also on hand to meet the children.
Previous send-offs have involved celebrities such as singer Sir Cliff Richard, presenter Denise van Outen, and Harry Potter actor Matthew Lewis.
The youngsters were chosen by doctors and medical experts, having battled with serious illness, disability and trauma. They are accompanied by nearly 100 doctors, nurses and physiotherapists throughout the trip.
The holiday will be action packed and every kid's dream, taking them to SeaWorld, Disney World, Universal Studios and more.
Myleene said: "It's been an absolute pleasure meeting the children here today. Dreamflight is a unique charity and it's been wonderful to see how excited the kids are to be flying to Florida in style on their own private British Airways' jet."
More than 5,400 children from across the country have been involved in Dreamflight holidays since the first trip in 1987. For many, it has been their first time abroad and also gives them a chance to have a holiday without their family.
The send-off was particularly pertinent for dressage champion Natasha, a former Dreamflight child. She said: "Dreamflight totally changed my life. I went from being such a dependent, shy child to a confident young lady and it's just great to see that it can happen to so many other people."
British Airways always teams up with Dreamflight to make the send-off extra-special. An army of volunteers are there to see the children off on the Boeing 747, including Darth Vader, some Stormtroopers, the Air Cadet National Marching Band and British Airways' cabin crew and pilots.
British Airways senior first officer Rebecca Statham said: "This is my first year flying the Dreamflight aircraft to Florida. The children are such an inspiration to us all, and I feel honoured to be part of the British Airways' team supporting this wonderful once-in-a-lifetime trip."
