One of the possible variable to consider is the future uncertainty of an unstable economy vs a solid strategy.
1. SWA is a 40 years solid reality, JB is a bit more subject to instability;
2. JB is expanding but unless JB accept the challenge and start to compete with SWA ... JB will never be able to grow as much as SWA, because SWA is already there;
3. Can JB compete against SWA? Not at the current status (and they do not even want to);
4. and yes depend on your age ... there is a possibility you will never be a CP in SWA ... but who gives a ******* ... QoL is the key ... and QoL is better in an organize company! ... like I said many of us would like to have your problem
