TUI operate with loads of over 90% all season and have flown to DLM and LCA before. They see Ryanair as no threat and have actually grown capacity to some core Ryanair markets a lot this year.
Ryanair will be out of DLM as soon as any marketing runs out. Cyprus will probably last with FR, Irish tourism there is currently 91% below its peak and has only started grow since Cobalt started LCA (first direct flight in years). Its more likely than not FR would not of considered PFO if Cobalt wasn't here given they have been operating out of LCA and now PFO for quiet some time and not started DUB.
