Bern
I calculate the Bern route to equate to an average of 11.8 pax per flight, LF 38%.
I know one flight went to LTN during fog, which judging by the CAA stats was carrying just 1 pax.
There may have been other cancellations I don't know of as there was fog and then high winds at the end of the month, in which case LF might be higher,
The Sat flight is new for summer. The drop in pax compared to the previous year can't have been helped by the lower frequency (8v11 p/w) and inability to make a day return on some days, but I believe frequency is now 13x weekly.
