Unless my memory is playing tricks on me (and it could very well be), wasn't Love Field turned into an entertainment complex for a while? I didn't live in Dallas, but I have a vague memory of that. Must have been before SW's lawsuit to put it back into service as an airport.
Talking back to myself here. I wasn't hallucinating, after all. The Llove Entertainment Center was in operation in the main terminal at Love Field from 1975 to 1977. Found these two squibs in google:
"This conversion came after the commercial airline traffic moved to Dallas/Fort Worth International Airport, leaving the existing airport terminal vacant. The Llove Entertainment Center consisted of a roller skating rink, dancing area, snack bar, exercise area and ice rink.

"The night DFW was opened, Southwest moved its operations from the yellow (north) to two former American gates in the green (west) concourse. Braniff also kept some of its Houston Hobby flights at Love and moved to the west concourse as well.
The City of Dallas, unhappy with the court's decision, made things as difficult for Southwest as possible. They closed off the terminal's main lobby and forced Southwest to set up a temporary ticket counter in the baggage claim wing (the only part of the terminal still open). Passengers accessed the west concourse through the connecting bridge American constructed in 1967-1968.
Meanwhile, the city tried to find as many uses as possible for the rest of the terminal. Portions of the yellow concourse were rented out to various general aviation companies, while Southwest put its tiny corporate office in a section of the old Braniff terminal. By the end of the year, all the abandoned jetbridges had been removed and Love Field was looking less and less like an airport.
In a last-ditch attempt to fill the vacant terminal, the extravagant "Llove Entertainment Center" (I have no idea why the owners put an extra L into "Love") was opened in 1975. The former ticket wing was turned into a bowling alley, while the beautiful main lobby was transformed into an ice rink. Upstairs, the Dobbs House Luau Restaurant was gutted and subdivided into two movie cinemas. Fortunately, the Llove venture proved unprofitable and it was shuttered in 1977.
At that point the city reopened the main lobby and Southwest was able to move its ticket counter to its current location - the site of the old ground-level coffee shop. By then the carrier had grown to serve all the major cities in Texas (Braniff had pulled out of DAL in 1976) and now controlled six gates on the west concourse. The other eight gates were sealed off."
