I don't think you are going to get in with less than the posted hiring minimums. There are 121 guys with the required time who are not getting the job.
MKE and ORD are the most junior bases. It seems like every new hire who goes to MKE transfers as soon as possible, so if you live in MKE that would be great for you. Good luck!
In regards to the $19.25/hr, I have flown around 450 hours this year with 530 hours of pay up to our July 7th paycheck. I get my one year raise in September, but I would be on pace to make around $26k if the $19.25 were to continue throughout the year. I usually have at least one or two days on a four-day trip where we fly less than 3:45. Our minimum pay is 3:45 per day, no matter what you fly.
So even though it is not very much per hour, you can live on it. Plus if you get the jet, you will be flying more and will have more options with open time at time and a half. Good luck!
