and yet there is no route to LCY so evidently those £150 return fares you keep quoting were not sustainable.
You also seem to be forgetting it’s a pandemic. Take my route LHR-ARN (Stockholm). I travelled weekly last year on the route. Pre Covid there were around 10 flights a day and times to suit everyone and I usually paid £100 return. Now it’s one flight a day on BA and one on SAS with a few cancellations as well and typical fares are more like £400 return. The market is in flux.
Pre-Covid there were millions of pax on that route per year and we’re still down to one flight a day.
You’d be best place to compare yourselves to Guernsey who outside of their own loss making state owned carrier have a flight to LCY and EDI twice a week (summer seasonal) and a Jersey link.
