Inter-island flying refers to the passengers booked to travel between Caribbean islands, who are not boarding or disembarking at London Heathrow.
The same aircraft will either start or finish its journey at London Heathrow, with passengers joining and disembarking at their chosen destination. Some passengers will stay onboard for the entirety of the journey (for example, from London Heathrow to Grenada).
If flying with us on one of these inter-island services, you'll be booked on an Economy Classic ticket.
