Ok I'll try to clear up some misconceptions.
First off let's talk about routes to London. Pan Am served ORD
as well as BOS
before the 1975 route swap with TWA (TWA gave up DTW
in return). Both carriers would continue to share LAX
. While Pan Am was always the exclusive carrier on the SEA
route. In 1980 after they acquired National, Pan Am began serving MIA
as well (National had been granted LHR
route authority in 1970). Around the early 1980s Pan Am was going to begin serving IAH
but pulled out before ever starting the route, since Continental began serving it. It was scheduled to be served with a L-1011-500. In March of 1991 Pan Am sold it's LHR
routes to United with the exception of DTW
. Since Bermuda II
specified only 2 US carriers flying to LHR
, Pan Am flew to LGW
, it also continued flying MIA
Ok so here's a summary:
Atlanta: No non-stop service, but rather a route interchange with Delta to London via Washington, lasted up until 1978.
Boston: service to Lisbon via Santa Maria until 1975, when these two cities became exclusive TWA due to the route swap.
Chicago: service to LHR
until 1975. ORD
was briefly served in the late 80s with an A310.
Los Angeles: LAX
and then in 1985 LAX
was inaugurated with a 747.
Miami: In the 60s service to Lisbon and onward to Madrid via San Juan was inaugurated but was cancelled in 1975 due to the route swap. Non-stop service to Frankfurt, London and Paris was inaugurated in 1980 due to Pan Am's acquisition of National Airlines. All these route swere served with 747s by the 1990s. After the Transatlantic routes were sold off to Delta in 1991, MIA
was the very last route served by the airline.
Philadelphia: non-stop service to London until 1975.
Portland: No non-stop service but direct service via Seattle to London.
San Francisco: non-stop service to London. Proposed service to Frankfurt in the late 80s that never started.
San Juan: non-stop service to Lisbon and onwards to Madrid and Rome up until 1975.
served until 1991.
began in 1985 with 747, while IAD
were also served.
