Yeah, it really depends. I've done it all different ways.

- Bill the client for actual expenses

- Paid out of pocket for travel that was baked into the day rate

- Had major travel (air/hotel) paid for directly by a client's travel agent. (Which I actually preferred to avoid when reasonably possible because now you're dealing with your client's travel policies.)

I'm not an accountant but I tend to agree you shouldn't be billing a broken-out travel line item that's not actual expenses or expenses plus explicit overhead [or a standard per diem].
