The average load on BRS-ZRH in June was 41. I don't know whether the Helvetic F100s are 100-seaters or 85-seaters to allow for the Viva! business class option.
The average loads have been noticeably higher each month this year (compared with the corresponding months last year) although still seem in need of improvement. Connectivity at ZRH would be an obvious boost as it would with some of the bmi regional routes to Germany.
I don't think that Helvetic has released any winter timetable details yet. Hopefully, the BRS has done enough to be retained but I would never bet on anything aviation-related.
Some of the Flyers have carried/are carrying Helvetic adverts and I noticed at least one First bus in the city carrying one too.
