Intl vs domestic reserve. You’ll get appx $1000 / mo perdiem flying intl that you won’t get sitting reserve domestic in sdf. That’s appx 25% more pay yr 1. I definitely noticed pay periods where I flew international vs domestic my first year.
Unfortunately, you will need to spend some of that in order to eat. We do have a tradition of buying meals for probationary folks, but I wouldn’t budget based off of saving perdiem.
