You would be far better off at an ULCC. If you need to come here for recently passed fed rides or something that is one thing, but I would jump out ASAP. Coming in as you are will look like forced upgrades, crappy commutes and perpetual reserve.
If you live in New York or Chicago it will be far more bearable. Lastly, flow for you would look like 5+ years at the low end, close to 9 at the high end.
