CAL is good for gettin 744 time and worldwide ops experience which are fairly valuable!
-but they do not offer a career, pay increases, loss of licence, retirement fund or seniority/advancement.
From what I ve seen most guys comin out of there have NO problem finding other jobs with the likes of NCA, CX, EK, Korean etc.
They might not have the most fantastic training - but it is based on Lufthanse SOP and syllabus - so not bad either -
