After my recent complaint and worries about flying with SmartLynx, I did get a call with a senior operations manager from Tui Airways and a Customer service manager on Friday they said that they could not tell me then but there was a major update to be announced on Monday morning for Summer 2020 which as obviously now been done.
They both said that in my case Cyprus would be available by end of July and that my flights to Paphos from Birmingham in September they were looking at combining that with the Larnarca service and using a 787 but were unsure which airport the flight would operate into. This does kind of make sense as PFO departs at 14:25 and LCA at 14:35 especially if pax numbers are not that high and it is only about 60-70 miles between the two airports
