In the 70s and 80s I think there were quite a few LGW flights from the U.S.

I believe --

TW to STL.
PE to EWR
EA to MIA (and possibly CO for awhile)
AA to DFW, RDU and then STL after buying TW
NW to MSP, DTW and at one point maybe BOS?
DL to ATL and I think CVG
Braniff on DFW before AA
Air Florida - maybe from MIA and MSY
National before being bought by PA

There was an Admiral's Club there for awhile as I recall.
