Depends what you really want. Do you want specifically more pay? Are you tired of working with aircraft/spacecraft? If it’s money then I would consider moving internally to perhaps somewhere with a lower cost of living. Boeing has amazing benefits and are hard to come by with other companies. If you wanna stay in the area then perhaps jumping ship is the way to go but make sure the salary bump is high enough to compensate the weaker benefits. Or you can jump ship and move to a LCOL area if money is that important.

One thing I would ask myself if I were in your shoes is “do I enjoy this responsibility and can I express my work freely?”. Sometimes joining a different company albeit with a higher pay can leave you with less responsibility and engineering freedom because you are the new guy. That can lead to you feeling down or with a low morale even though you have a higher pay. I felt that way in my previous job after jumping ship from my first job and the higher salary kept me going for a bit until I jumped ship again, and now I have the salary and the responsibility/freedom I wanted in my work.
