Gee, do all that in three weeks, remember none of it and (worst case scenario) end up in what the yank cop shows call A Situation with no effective skills, and all for $36K pa
Or, jump onto Seek and find a bunch of retail jobs paying $35-55K pa where you can be home every night and won't end up in front of the ATSB justifying your actions when it all goes pear shaped.
[sarcasm mode off] Avigirl, I don't think anyone is having a personal go at the individual staff members (I'm not, anyway) but at Jetstar itself for the questionable training, pay and conditions they provide for cabin crew. Probably the bulk of Jetstar staff are doing the best they can under the circumstances, but the training regime you describe is substandard and it's no wonder staff can't remember procedures or go to pieces in an unusual situation.
Conducting a safety based course in three weeks that takes every other provider 5 smells fishy, even if they do have an all star cast of applicants. It's not something Jetstar should be proud of, whatever spin they choose to put on it.
