I dont know the dates, but for a long time F9 served ELP as a tag from ABQ. Then from DEN nonstop on Lynx. I never flew the nonstop but the ABQ-ELP runs were far from full everytime I flew. I think F9 cut ELP before UA started service from DEN, so I don't have high hopes for F9 returning, more likely is WN giving it a try.
