Internal recs don't count at Southwest, at least not until after the interview. Even after, they're not required. If you interview well, you'll get the job. I had no internal recs and got the job, and I know several others in my shoes. The total time is your problem, in my opinion. Keep flying and once you swing over 5-6k you're gonna get a shot. Who knows, maybe even earlier. They've had a slowdown in interviewing and hiring since the MAX grounding, so they can be more picky. I'm sure they'll lower their requirements once hiring gets back in the regular pace.
