Abu Dhabi-based Etihad Airways will boost its services to London Heathrow during summer to meet increasing demand during the period.
The airline currently operates three daily Airbus A380 services between both capital cities.
Between May 26 and June 22, four daily flights will be operated on the route, increasing to five from June 23 to September 28, Etihad said in a statement.
The service will return to four daily flights from September 29 to October 26.
The additional flights will be operated by a two-class Boeing 787-9 Dreamliner, which features 28 business class seats and 271 economy seats.
Etihad, which reported a $1.28bn loss for 2018, down from a $1.52bn loss in 2017, launched a five-year turnaround strategy in 2017.
It has since undertaken numerous changes to restructure its operations.
