For what it's worth, I'm junior and was hired on the downward side of the hiring bell curve. There really is no point in seniority projection exercises. At the end of the day, if it makes financial sense and you like the idea of coming over here, come on over. Nobody in my hiring class is fretting over not having a quick upgrade time. You'll have your choice of 4-5 aircraft types to fly within about two years (A220, A320, B717, B73N, 7ER). That's already a lot more variety. Our reserve rules are great, especially if you live in base. Our pay rules are completely different than WN but in a way which I think makes more sense. I have worked at both DL and WN in non-pilot roles a decade ago and am confident that DL is the better place to be.
