Delta senior vice-president for Europe, Middle East and Africa Nat Pieper said the airline has been forming a closer relationship with Virgin brands following the signing of its code-share agreement with Virgin Atlantic in 2014.
With a new Edinburgh-New York JFK daily flight set to launch in May this year and following the start of a Manchester flight to the same US destination last summer, he said the airline was performing strongly.
Pieper added he is hoping the relationship with Virgin will allow it to grow its brand in the UK.
He said: “We’re trying a number of things with Virgin… (we’re hoping to) leverage the Virgin Holidays brand.
