There used to be a lot of summer charters, from PIK Lourdes as a for instance.
Along came great the God Ryanair, charters no longer welcome.
Lots of Lourdes in the last few years from EDI , with a few from GLA .
Jetway operations at both these airports, a friendly welcome.
Go back to PIK ?
Very unlikely !
You chose Ryanair, your risk, I can't see any charter operators going back.
