I agree with this advice. Aviate is by no means a guaranteed job with United. It may be the easiest path because of no interview but it may not be the quickest path. You’ve already been hired by a regional and have a job offer at a LCC so it seems like the interview part won’t be an issue as long as you keep your training and discipline records clean. Take the LCC job and keep your apps at your dream jobs very updated and you’ll probably be fine.
