Italian airline Neos began flying non-stops from JFK to Palermo twice weekly in early June. The schedule continues throughout the summer. Neos has already announced its plans to increase the service to three flights weekly in 2025.
New York JFK - Palermo PMO non stop by Neos, aka the “Godfather Express”
Newark EWR - Naples NAP non stop by United, aka the “Sopranos express”
A flight for every film/TV series season, that is why they are called “seasonal” flights.
There were rumors about United resuming the EWR - PMO as well this year, but it didn’t happen. Maybe next season.
