It looks a carbon copy of this year
Tues. Palma. Volotea B717
Thu. Ibiza. Volotea B717
Sat. Palma. Volotea B717
Sat. Mahon. Flybe DHC8
Could be that TUI reschedules the Flybe flight next year depending the outcome of there involvement of 3rd party flying
Regarding any extra flights or new destinations I think that TUI have probably finished launching there summer 2020 programme, the last bit was done in July 19
