Grow up, people - you want to fly for Southwest Airlines - the best employer in the United States according to numerous surveys?
Then go here.
SWA Pilot Jobs - and you'll see that not only is there an administration fee (in common with almost all SU airlines) for applications; but you're required to come with a 737 rating - or at the very least least be prepared to get it (at your expense) if you're selected.
Southwest Airlines requirement on the B-737 Type Rating: Although preferred, a candidate may apply without a B-737 Type Rating. If a candidate interviews and successfully completes the entire selection process they have 6 months from that date to successfully complete a B-737 Type Rating course and obtain a B-737 Type Rating to be eligible for hire.
I suspect that most, if not all, European airlines will be watching this with great interest and if it's successful will have no hesitation in pursuing a similar tack with their pilots. BA in particular has apparently been looking at this for some time.
I believe that this is the precursor to piloting becoming a true profession - in other words, one where there will be far greater movement of personnel, each of whom will be employed strictly on the basis of ratings already held. In the same way that in the IT market the onus is on the individual to ensure that s/he is trained (at their own expense) on whatever the most sought after process is - SAP, RSA or whatever - then so it will be the responsibility of the pilot to obtain new ratings.
I also foresee the abolition of the seniority system, which will assist in the freedom of movement - people will be employed for specific roles in specific types; and when that type is no longer used their services will no longer be required.
The upside is that airlines will be prepared to pay more money to compensate for this - and for the cost of the benefits (medical, insurance etc) which will then become the individual's, and not the company's, responsibility.
Interesting times ahead, people!
