Business class-only airline Silverjet is adding a second return service between London Luton and New York Newark from September 23.
The new service departs Luton at 4.45pm and arrives 7.45pm, and the return flight departs 9.45pm and arrives 9.45am.
Chief executive Lawrence Hunt said the airline enjoyed an 80% load factor in August and is seeing strong forward bookings.
He added: “We are seeing a good mix of business and leisure customers which allows us to spread our risk.”
