Except that in BA or LH, cadets fly a 320/737 for years, making thousands of landings before going to a widebody.
After 10-15 years, our cadets become widebody Captains having done less landings than I did in my first year of flying.
4 or 5 years of being an SO right after school certainly doesn't help.
KA is actually much safer in that regard.
The good safety records at CX mainly rely on having a good mix of experienced and cadets crew.
Crew 100% of the flights with cadets and we are no different than other airlines in asia. Let's be realistic, they don't have a good safety reputation.
Good at following procedures, yes. Handling the jet or thinking outside the box? No.
