Delta Per diem question
 

On the info page for Delta it lists per diem as $1.85 per hour domestic per diem. Is that per flight hour or hour on the road? As an old MAC crew dog I do know per diem, but I am a rookie in this world. Thanks,

Measured by "Time away from base". I.e. a two day trip starting at noon on Monday and ends noon on Wednesday, will pay you 48 hours per diem (domestic for you, more if you go international).

That's not bad at all.
