Jazeera Airways Chairman Marwan Boodai commented:
“Jazeera Airways has been building a great reputation in the Middle East in the low cost airline sector, offering a strong alternative to the legacy airlines.
“We look forward to serving the UK market, and extending consumer choice to Kuwait and the Gulf, with our value proposition. This is a first for an LCC in the Middle East to fly long-haul, using the A320neo aircraft.”
According to the airline it is the first new service from the UK to Kuwait in 55 years.
It highlights that the route will provide onward connectivity to Dubai, Bahrain, Doha and Delhi.
Earlier this year Kuwait Airways announced plans to increase flights to Heathrow by 30 per cent this summer.
