IMHO, Get the ATP and get into bigger equiptment, turbine if you can. Believe me I know it's easier sad than done. I'm furloughed airline that had 10 years seniority. The pay may be less now but as the years go on you do want to be competitive with other pilots. The more experience the better. In the airline industry seniorty is everything. The sooner you get hired the more secure you are. I'm assuming you want to go the airline route because you accepted the previous job. Don't worry about washing out of the last job, it won't hurt you as much as you think if you don't let it. It's a life lesson and will make for a good conversation during an interview. Now if your happy where you are and think you want to stay there for a career then by all means stay. But since you asked the question I'm betteing you want to move to something better.
