Theyve coped without Ryanair and their antics up until now so they'll cope again going forward and have reserves and capacity when others will reach gridlock and plateaeu.
LH for example, so far, seems to be doing ok on FRA (which might have been marginalised with longer term FR competition), plus the apparent EZY suggestion of expansion will do no harm. Once PIK goes, the landscape/politics and Ryanair shenanigans may take another turn.
Still some FR non based flying continuing.
