What nearby airports should I use if I'm trying to get from Indianapolis to Mannheim, Germany

What nearby airports should I use if I'm trying to get from Indianapolis to Mannheim, Germany?
I think Mannheim's airport is small, therefore ticket prices are more expensive. Should I fly into Frankfurt or another airport? Also, should I fly out of Chicago Midway or O'hare/ Cincinnati, etc. for a cheaper flight? I think Mannheim's airport is small, therefore ticket prices are more expensive.

ORD or CVG to Frankfurt will probably be the cheapest.

Dohop.com has a great map of airports. I you go there, input your airports, and click 'map' (just above the from box) you will see the airports you selected and can find bigger airports nearby. Dohop has great prices for international flights by the way, and also, if you want to search from multiple airports you can, just by entering a comma after the first one you put in. Long story short, Chicago O'Hare and Frankfurt might be good bets.

For a domestic flight do you only need to have your bags checked once

For a domestic flight do you only need to have your bags checked once?
I'm going from Indianapolis to Richmond soon and there is no direct route so I have to connect in Atlanta first. Do I need to have my bags checked again? I'll be using AirTran.

In my experience with AirTran and connector flights, I've only had one bag check-in. The baggage handlers will transfer your bags from plane to plane in Atlanta. I hope that helps :)

How Long Does It Take to Fly From Indianapolis to New York City?
I'm going to New York in the spring, and it will be my first time on a plane. And I'm completely petrified. I don't want any "Oh, don't be scared, blah blah blah" answers. All I want to know is how long the flight will take so I can be prepared.

Arrival 2 hours before departure in Indianpolis is required for international check in as your passport information will be taken in Indianapolis and may be subject to re-check at the Philadelphia gate. This is US Airways suggestion.
