Flyinrob - If you got your email from Delta with your flight information, that will more than likely be the last thing you hear from them before your interview.
A few other tips? Try to be at the interview building by 7:30am - there was a long line to check in the day I was there. Bring an extra shirt for your interview suit - you'll be wearing it again on Day 2. Make sure you eat breakfast that morning before you leave for the interview. Bring some Power Bars in your briefcase. There's a cafeteria in a building across the street that they'll send you to for lunch, but otherwise there isn't any food available throughout the day, and it's pretty stressful and can get exhausting. They will mention to you to take breaks when you need them - step outside, get some fresh air, get a bottle of water, etc. Take them up on that offer. They mean it, and you'll need it to continue working with a clear head. It's a long day.
Good luck!
