hi there,
If Wilmington is where you are headed first, you might consider:
-The flights to Delaware that arrive at the Philadelphia International Airport. It's just a half-hour drive from Philadelphia to Wilmington, and only about an hour and thirty minutes to
Dover.
- Baltimore Washington
International airport will have you within a 1 to 3 hour car ride to pretty much all corners of Delaware.
- You can also compare the flights to Delaware that land in Washington D.C. There are two major airports there, though the trip into Delaware thereafter takes around 2 to 3 hours.
