Have they fixed the BAe-146 organophosphate poisoning issue yet?
Smelly little things - that sweaty socks / labrador sick smell is due to contamination in the cabin conditioning system. BWoS allege that it's no problem, but several pilots apparently suffered long-term ill-health after flying the 146 for a few years.......
In the RJ85 version used by Lufthansa Cityline, there's a high pitched whistle in the front cabin somewhere over Row 1 which is maddening - but it isn't present in the old 146 used by Lufthansa Eurowings.
The only technical delays I've had in several hundred flights with Lufthansa have been on the BAe146 / RJ85.
