What I have found is that an I class to HEL on the outward, can be combined with an I class from WAW,PRG or BUD on the return (but not VIE or ZRH).
Meaning, I can fly LHR-HEL and WAW-LHR for little more than £300 in CE.
And the HEL-KBP KBP-WAW fare is about £700 on PS (operated by AY on the HEL-KBP sector).
