Not strictly true. EJ regular run an internal scheme with a very heavily subsidised TR. In year one 90% were cabin crew, year two 50% cabin crew. So it it not true to say EJ don't appreciate it. You might learn anything about flying the plane, but your CRM and no techs are pretty top notch. You'll learn much more about it being crew than reading a few power point slides on your MCC/TR and airline induction (if and when that ever happens).
