Ok well, kiwi.com is literally only a search engine for #Ryanair...and I don't fly with them.
There is no chance to pre-filter certain airlines out of the results. No thanks!
#Skyscanner however isn't so great either
That leaves me with Google Flights which surprisingly is the "least useless" of these three.

Any other recommendations?

is there a better #skyscanner with more filters, search options, etc? i’d pay for that search
