Jersey's mail plane touched down for its last delivery this morning (4 Aug)
Royal Mail scrapped the service last month as it tries to fill a £1 billion black hole in its finances.
It said it was no longer 'commercially viable'.
"Instead, both services [Jersey Post] 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"
Royal Mail began considering the mail plane's future in May when it opened an online consultation, but says only 25 people responded.
The service will keep going to Guernsey because of the online greetings card companies like Moonpig and Funky Pigeon which operate in the island.
Jersey Post CEO Mark Sivert says that most islanders won't notice much of a difference.
"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."
