For the cities with multiple airports (DC, NY, Chicago, etc.), just have once choice - "NY" as opposed to "NY - JFK" and "NY - LGA". Your target user seems to be someone who is more interested in getting from point A to point B by the cheapest means possible, as opposed to someone who's going to fly there - in which case they would think of their origin as (for example) New York, as opposed to La Guardia.
I would also add travel time in there - time is money, and it's not much good saying that it costs $70 in gas to drive somewhere if you don't also mention that it takes five days.
If you really want to get fancy, add an option for the full cost of the trip, for lack of a better word - meaning that the plane price includes travel to/from the airport (making reasonable assumptions about cost) and the car price includes accommodation as needed.

Or maybe offer one choice: "NY", and present the different results alongside car and bus options.
Plane: $119 from JFK, $134 from LGA.
Car: $52 in gas.
Bus: $68
I didn't think about presenting it in that fashion, thanks for helping out!
Travel time and adding in the additional costs (checked baggage and such) would be useful, thanks for the feedback!
