I say go for it, but it important to know
If you are in the front you are responsible for your own actions and safety.
The chaps at Lion have a set of controls infront of them.
Neither of that matters. For the statements to be effective you need to have a standard. Lion Air hasn't got one.
Lion presents a good chance to log plenty of hours in a short period of time then applying to a major carrier.
It has been regarded as the last chance saloon for the fool and his money. I have seen the 'standard' of the Lion Air product and IMHO I would be happier with someone who has 500hrs on Microsoft FS and a copy of the B737 FCTM. Simply 'logging' 500hrs on a 737 doesn't mean you will gain any relative experience. You will probably be tainted for life and need considerable retraining, if you ever get the opportunity. These so called 'major carriers' are running a mile, believe me.
