The saying is...
The grass always LOOKS greener.
Left the North Sea as 10yr Capt As332L to fly BAe146 and within two years even as a F/O was on the same pay. that was 1989/91. Helicopter salaries have come up alot since then. And Low fare airlines have kept salaries down
Yes the Fixed wing days were easy with all the support you needed and a great social life. But 'security aspects' have changed it all.
Each airline has its own very individual idea of Helicopter hours. Debonair for example I recall required 3000hrs for command but said none of my twin IFR helicopters time could count!! but someones cessna 150 vfr only time did!!
If you've done all there is to do with Helicopters go Fixed wing. Go for it. Tell us how you get on.
