Royal Mail has confirmed it will be pulling the daily mail plane service from August.
It will land in the island for the last time on Friday 4 August, with all mail delivered by ferry from Monday 7 August.
The move will mean any post will take at least two days to be delivered.
In a statement, Royal Mail say:
"Following discussions, Royal Mail and Jersey Post have concluded that the provision of the aircraft is no longer commercially viable for both parties. Instead, both services will use the pre-existing ferry service to send and receive post from the island. This will result in a two-day service.
The decision will reduce costs for Royal Mail, amid a steady decline in letter volumes, and reflects a commitment to reducing the business’ reliance on flights as it works towards a 2040 net zero target."
The UK postal service launched a consultation in May to explore 'the implications' of changing how mail gets to the Crown Dependencies.
Only 25 responses were received.
Jersey Post CEO Mark Sivert says most islanders will not notice any difference.
"The reasons for ending the dedicated mail plane are clearly set out in Royal Mail’s consultation document. Nonetheless, our responsibility is to our customers, our priority is to find solutions for those impacted.
We are using our expertise, extensive logistics network and partners to achieve the best possible outcomes."
