Yes Palma has seen a fairly large decrease year on year since the high point in 2016. On the TUI website there were no options for Flybe flights to Palma in 2019 that I could see, so I wonder if this summer will mark the end of the road for Flybe E195 sun routes.
There's always the hope that EZY might do something in summer 2019, but I really don't want to kick off that particular discussion again as it's been done to death on here!
Maybe Lolo will go for the mass market and swap Pristina for Palma...
