JetBlue Airways‘ is finally making the hop across the pond.

The New York-based carrier is now selling tickets for service from its home base at John F. Kennedy International Airport to London Heathrow, starting Aug. 11. After its debut, it plans to add flights from JFK to London Gatwick on Sept. 29.

JetBlue’s plan for London service has been in the works for more than two years. Executives have said the trans-Atlantic market was ripe for disruption, particularly with lower business-class fares than competitors offer. The airline in February unveiled its revamped Mint business-class cabin that will feature suites with sliding doors for the London flights as well as some other longer-haul service.

The airline took delivery of its first long-range Airbus A321LR last month that will be used for the flights.
