Not to change the subject or get into an argument but it bears mentioning that I know a few guys w/737 type and 0 hours who got asked that question a lot by interviewers. Is a 737 type with no hours worth anything? Maybe...it would help in the sim portion of an interview. I had never set foot in a 737 cockpit and thought the UAL sim portion was easy.
A good personal friend ( a guy also on APC forums) talked with a lady on the hiring board at DAL and she said that 737 type tells her one thing: SWA is their first choice. I got my type for 1/3 the cost in a Seminole over 2 days. A lot easier and cheaper.
My 2 cents. Personally I decided not to spend the extra $$ on something I didn't think I needed.
Cheers.
