I just checked my 2 Braniff timetables from '81 and '82, BN was not serving ELP then.
As for Continental's hub at ELP, when they merged with Texas International in mid-1982, here are the cities each served from ELP:
Continental: Albuquerque, Austin, Denver, Las Vegas, Los Angeles, San Antonio
Texas International: Houston-IAH, Midland/Odessa, Phoenix, Tucson
There were a combined 22 daily departures between them.
In terms of cities served by the two of them at the time, ELP was the third largest market behind DEN-Stapleton and Houston-IAH.
