Canadian carrier Westjet aims to add more low-cost transatlantic flights following the launch of services from Gatwick next year.
Chief executive, Gregg Saretsky, told the Financial Times that the airline was in talks with other airports in Europe such as Paris, Amsterdam and Rome.
It is also considering other UK destinations, including Manchester and Birmingham.
WestJet already flies between Dublin and St John’s in Newfoundland, and began flights in May between Glasgow and Halifax in Nova Scotia.
Its transatlantic business plans to introduce a fleet of four long-range Boeing 767-300s.
“This is the first piece of a new growth plan for WestJet,” he said Saretsky. “Bringing low fares to long-haul travel – this is something the world is just starting to see.”
The airline announced plans in June to start flying between Gatwick and six Canadian cities from spring of 2016 with fares starting at £163 one-way, including taxes, fees and surcharges.
Saretsky said the airline targeted a return on invested capital of between 13% and 16% for its long-haul business.
“We’ll test that premise, and if it’s successful – as we expect it will be – then that becomes something we can extend to other geographies whether it’s continental Europe, Asia or Latin America,” he said.
