To put things into perspective for your people who are looking into this job.
At my current European Loco airlines (not the one that shall not be named) I know of 2 young F/O's (25 ish) who have cashed out and are heading back to university. These are people just like you, who started flying out of passion. 6 to 7 years later they're all looking for a way out.
Unless you manage to land a job at one of the legacies you're looking in at the wrong industry for a career. Even If you manage to land a 737 job at your homebase, there's no future in it. Or are you going to do 35-40 years of loco short hauling?
