As somebody that has commuted for a majority of my 20+ year career, I would not recommend doing an international commute as 1) A new-hire and 2) To a domestic NB position. NB trips often start much earlier than WB trips and end much later at night at Delta and being junior, you will most likely end up with those in the beginning. This would mean you would need to come to work a day early and pay for a hotel or have a crash pad. I believe you also need to list for a jumpseat at least 24 hours prior for international jumpseating, which can complicate last minute schedule changes and re-routes (which you will be subject to A LOT at Delta). You would potentially be spending the last day of your trip in a hotel/crash pad as well. International commuting is doable, but it is MUCH easier after you have some seniority or can get onto a WB category... just my 2c.
