You live in a United domicile and are considering switching to UPS. Yes, you could make more at UPS and retirement benefits are better, BUT you struggle with night flying. You would be trading no commute for an easy commute. You would be trading very good pay, for even better pay. You would be trading rarely flying at night for the certainty of it (international flying and the majority of our domestic involves night flying). If you are intending to bid international at United, you are willing to give up day only flying for more money. In that case, consider UPS where you can do that for a larger chunk of your career. If you were never intending to do that, stay at United.
