just get that 737 type rating......you are golden.
No.you will probably have 1500 hrs by the time you are active 6 years, or close to it , as I did, then go for the 737 type rating......got my commercial right out of flight school with the FAA competency test....great gouge out there. once you get your ATP and have the 737 type....you are looking good, hope you like airports!
The only thing a 737 or type rating without any hours flying the plane shows is that you are trainable in multi-piloted transport category aircraft. In other words - not a hell of a lot.
You need total time, multi time and PIC to get hired at a national or regional airline.
You need a AMEL, ATP minimums and a pulse to get hired at a regional airline.
