The first budget transatlantic flights

In 1955, a small Icelandic airline, Loftleioir Icelandic, slashed the cost of flying across the Atlantic.

For the first time, thousands of young Americans were able to afford air travel to Europe on what became known as the 'Hippie Express.'

In 2017, Mike Lanchin spoke to Edda Helgason, whose father, Sigurdur Helgason, launched the ambitious scheme, and Hans Indridason, who ran the company's sales and marketing department at the time.
