Actually sir, you should check YOUR facts. The "gateway" system that NetJets uses requires the pilots to choose from a list of company approved cities. Yes, the pilots choose, but the company gives them the cities they can choose from, which was the subject of his post. Inquiring how the companies determine which cities they approve for use as gateways or domiciles.
CitationShares does the same. They have a list of approved "domiciles" and requires you to live within 90 minutes of your domicile. Again, the pilot chooses, but he must choose from the choices the company makes available. NetJets, Flex Jet and CitationShares are similar in this regard. However, NetJets is different in that the pilots are not required to actually live in their gateway city. They are just required to be there by midnight of the night before their tour.
Here are the NetJets approved gateway cities, as listed on their website:
Columbus, OH; Bradley, CT; Teterboro, NJ; Washington Dulles; Atlanta, GA; Orlando, FL; Minneapolis/St. Paul; Denver, CO; Dallas, TX; Las Vegas, NV; Boston, MA; San Diego, CA; Seattle, WA; Midway, IL; Pittsburgh, PA; West Palm Beach, FL; St. Louis, MO; Los Angeles, CA; San Francisco, CA; Salt Lake City, UT; New Orleans, LA; Charlotte, NC; Jacksonville, FL; Detroit, MI; Phoenix, AZ.
Here are the CitationShares approved domiciles from their website:
BOS, HPN, EWR, BWI, ATL, MCO, FLL, MIA, ORD, DFW, DEN, LAX, SFO, PHX, CVG, SAT, STL, BNA, MCI, IAD
Flight Options has a little different concept, where they are allowed to choose any city served by a certain number of airlines and flights.
The criteria the companies use when approving cities for domiciles or gateways have to do with the cities having a certain number of airline options, as well as the price structure at these airports, and to a certain degree, if the airports are prone to big delay or cancellation problems.
