The company is not paying 4X to cover trips. The only time the company pays 4X is if the invoke 23m7 and skip PAST QS to something else (generally IA). A standard 23m7 pays single pay to whoever was skipped (regardless of what step was skipped) and double pay to the QS pilot who flies the trip. Skipping QS pays single pay to both the originally skipped pilot and the skipped QS pilot, and double pay to the operating pilot. While lots of IAs have still been going out, at least in my category, each time it has been because QS was run but there were not takers. In that case QS was not skipped so the IA does not required 4X pay.
