Branson explained that he had started Virgin Atlantic, Virgin Australia and Virgin America because of his dissatisfaction with the flying experience and service on other commercial airlines.
"As more airlines consolidated and grew larger and more focused on the bottom line, flying in the US became an awful experience," Branson wrote.
"Virgin America became the first airline to offer fleetwide WiFi, soothing mood lighting, touch-screen seatback entertainment, an on-demand food ordering platform, and power outlets at every seat on every flight. Our unique and stylish product and brilliant customer service have won every major travel award," he wrote.
"The airline has also done something almost inconceivable in the airline industry: Virgin America won the hearts and fierce loyalty of consumers around the country. People love this airline."
