Quick question. I'm flying ATL -> CDG -> BUD on DL, with a little more than one hour stop in CDG to change planes. I don't have to go through customs in CDG if I'm not leaving the airport, correct? I just hop on the new flight and do customs in BUD?

That's how I remember it working from other trips elsewhere, but just checking since I'm a little nervous about the trip now. And while I'm at it, anything in particular I should know about customs in BUD? I'm assuming (hoping) that some of the agents speak English there, and that I can get a customs card with English translations. I've only flown into AMS and LGW before, and not had to worry too much about the language barrier.
