Frequency is being boosted by Etihad Airways from Heathrow to Abu Dhabi.
A fourth year-round daily service is being introduced on October 27.
The new late evening departure from Heathrow follows the introduction of additional seasonal services this summer.
A two-class Boeing 787-9 Dreamliner will be deployed on one of the four daily London services.
The aircraft is configured with 299 seats – 28 business studios and 271 economy seats.
This will complement three services operated by 486-seat Airbus A380s.
Etihad Aviation Group chief commercial officer Robin Kamark said: “The flagship Abu Dhabi to London route is tremendously popular with point-to-point business and leisure travellers, and those transiting beyond our hub and we recently boosted frequencies between the two cities to meet increased demand at peak travel times.
“Adding a fourth year-round flight will provide much needed capacity and optimised timings and easy connections to key destinations across the Middle East, Africa, Asia and Australia.
“The new service demonstrates our commitment to the crucially important UK market, and ensures we provide our customers with all the benefits of a next-generation fleet across all 42 weekly departures to and from the UK.”
Etihad Airways also operates two daily Boeing 787 Dreamliner flights between Manchester and Abu Dhabi.
