Citation Shares has MCO as an Domicile. It's not really a gateway. Last time I talked to someone there he said they only had MCO and White Plains as domiciles. He also sais they may get gateways in the near future. Hope this helps.
Got a BLAH BLAH BLAH letter in the mail today from Citation Shares that says they have aircraft based in: White Plains, NY (HPN);Orlando, FL (MCO); Miami, FL (MIA); Fort Lauderdale, FL (FLL); Atlanta, GA (ATL); Baltimore, MD (BWI); Newark, NJ (EWR); Boston, MA (BOS); Chicago, IL (ORD); Dallas, TX (DFW); Denver, CO (DEN); San Francisco, CA (SFO); Las Angeles, CA (LAX).
