Etihad Airways is adding a fourth daily flight between Heathrow and Abu Dhabi over the festive period.
The increased frequency will run from December 15 until January 13 next year.
The additional flights will be operated by a two-class Boeing 787-9 Dreamliner with 28 business studios and 271 economy seats.
Etihad Airways currently runs three flights a day on the route with three-class Airbus A380 superjumbo aircraft.
The airline also recently announced seasonal frequency increases and aircraft upgrades on a number of key routes to meet increased demand over the peak winter period from its UAE hub including additional capacity to Bahrain, Belgrade, Cairo, Istanbul, Medina and Kuwait.
UK and Ireland general manager James Harrison said: “We are thrilled to announce more flights to London over the festive period. This is a busy time for local guests travelling between both capitals and the extra service will allow more choice and flexibility in their travel.”
