Yes Eastern did indeed use both Kansas City and Houston Intercontinental as hubs. Kansas City was mainly used to connect east to west traffic. It helped offset Eastern's extensive route structure (which was also extensively seasonal) on the eastern seaboard. 727's, DC-9's. and 757's supported this operation. I don't recall one widebody. They used IAH as their "Moonlight Special" headquarters. A300's shuttled cargo around at night and took passengers along at cheap fares and no frills. I thought this was an excellent idea especially with Continental being at IAH. Had Texas Air have been thinking, this would have been a great location to connect the two airlines. However, IAH was downsized and the "Moonlight Special" was moved to ORD. ORD was not near the size that IAH was and did not last long. It eventually ended around 1988. MCI was closed in 1989 and Eastern eventually returned to Houston by way of Hobby, not Intercontinental. It's strange to have had a hub somewhere and eventually not even serve that airport anymore. Eastern also closed down their entire operation at JFK, including all passenger and maintenance services. Other not so known hubs that come to mind....TWA at MCI, CDG, and ATL, Republic at PHX and ATL, Texas International at DFW, United at CLE, Delta in Memphis, USAir at SYR, Air Florida at TPA and MIA, New York Air and Presidential at IAD, and People Express at EWR.
