They’re a relatively new company. I’d definitely contact the ownership and express your concerns. Hell, a large part of what I learned in those webinars was listening to guys like you, with 121 experience, answer the questions. Most of the instructors are military transitions to the 121 world and carry the same edges and faults I have.

also, this place is awesome. I’m having a great time so far.

I sat through a Spitfire presentation, in which they addressed the LOI. Their LOI demonstration was way to technically heavy for the Southwest LOI. The Southwest LOI is about CRM/human factors then how long can we hold if we burn 6000# an hour. They also didn't mention the Southwest LOI debrief, which I'm convinced is the most important part of the LOI.

I recently interviewed and got the job. I did interview prep and found it beneficial to the degree it helped me polish my answers. Sometimes even raw talent needs coaching/refining.
I used Vicki Ross and Flight Path Vectors.

As an alternative to paid services. Here’s what I did. My friend was interviewing at a different airline the same week as me. We talked on the phone for about an hour or two discussing TMAAT situations and HR type questions. It helped because we flew together/with the same people at a previous job and we could help each other refine the TMAAT’s. Not so that they were memorized or rehearsed, just kept the details fresh in our minds. A lot of the paid for advice is out there open source on the internet, just gotta sort through the junk for it. It worked out for both of us. He’s wearing a double breasted jacket and I got a free shot of wild Turkey.

I've heard nothing but great things about her. She seems to be the go-to for SWA interviews.
