Lao Skyway flights between Phonsavan (XKH) and Vientiane

Does anyone have any info on whether Lao Skyway is still running flights between Phonsavan and Vientiane? I saw that they were selling tickets for this itinerary in September, but I don't see anything available for October. I was hoping to fly between Vientiane and Phonsavan to avoid the long van ride, but if the flight is not running would the van ride be more comfortable from Luang Prabang, Vang Vieng, or Vientiane?
