The first new WestJet Boeing 787-9 Dreamliner has been introduced on transatlantic service between Gatwick and Calgary.
New long-haul business class seats feature on the new generation long-range aircraf with 16 private pods with lie-flat seats.
The aircraft carries 320 passengers in a three-class configuration.
The Dublin-Calgary route will be flown by the Dreamliner from June 1 with the aircraft also being deployed from Paris.
Gatwick chief commercial officer Guy Stephenson said: “The launch of the 787 Dreamliner will offer around 24,000 more Gatwick-Calgary seats per year on the same number of aircraft, and its highly fuel-efficient engines will also help us in our ongoing mission to become the UK’s most sustainable airport.”
The Canadian carrier’s chief commercial officer Arved von zur Muehlen said: “Today is a fantastic day for WestJet as we take this important step in our journey to become a full-service global network airline.
“The London market has quickly become an important one for us with service from six cities across Canada.
“It is no accident that the first transatlantic flight on the Dreamliner is to our largest international market, from our largest hub and home in Calgary.”
