The carrier has been flying to the Caribbean island nation for over 20 years, but will cease the service next June.
In a statement the airline said:
“As part of a recent network review, we’ve evolved our Caribbean offering, to ensure we continue to serve destinations most loved by our customers.
“The proposed changes mean we will increase flights from London Gatwick to Antigua, boosting services from three per week to four per week, from June 8, 2020. Our Havana service will also move from London Gatwick to Heathrow and will remain the UK’s only direct scheduled flight to Havana. The service will move onto the A330-300, increasing Upper Class capacity by 63 per cent and will open up more hub connections from across the UK.
