Thanks alot.

Since AA pulled out of ARN, it is somewhat difficult to get AA credit going into ARN. I could fly Finnair to HEL, but this means a two-hour Chinatown bus ride from Philadelphia to NY first, since Finnair only flies out of JFK.

Money is definately an issue-I'm a college student!

What about planning and executing runs? Are there any major differences between AA and NW that are worth taking note of?
