So what is the metropolitan area with the three airports, with one being twice as far as the other two? Maybe Miami/Ft. Lauderdale/West Palm? Perhaps La Guardia/JFK/Newark? Dulles/Reagan/Baltimore? Oakland/SFO/San Jose? The letter writer is excluding a key piece of information here. How can we provide advice if we don't know the exact airports she is referring to? I don't want to have to model every scenario with all the airport possibilities; just tell us the metro area (as well as your brother's home airport so we can analyze the routes and fares).
