More interesting than that it seems: PIK-RZE is £8 on all flights until 23 February inclusive, and then from 26 February and onwards it drops to £6. It seems detached from the fares since within that period you can have higher fares on £6 and lower fares on £8. The RZE service then stops on 30 March, and switches to Bydgoszcz, and stays at £6.
There's something similar on EDI-KRK, so they get £6 from 21 March (which has a £130 fare on that particular day as it happens), hence a different date, with £8 on all fares on and before 19 March.
