Pete, the stats don’t tell the full story. The programme for 2017 went on sale quite late and loads suffered as a result.
This year figures are looking much improved, the overall average for the Embraer routes on the last set of figures was about 63% although that was dragged down by Glasgow which is quite weak and quite frequent making up about 17% of all flights. The last set of figures for Budapest specifically was around 90 per flight (76%) which isn’t bad at all, as you note fares tend to be higher than EZY and awareness not as strong.
