The document discusses trends in the airline maintenance, repair, and overhaul (MRO) industry to help airlines reduce maintenance costs. It notes that airlines are under pressure to provide more for less due to competitive passenger fares. This has led airlines to look for ways to reduce maintenance costs, which account for around 11% of airline operating costs on average. The MRO industry is working to provide airlines with solutions like one-stop shop maintenance services and fly-by-the-hour service contracts to help lower costs. It is also consolidating MRO networks and exploring ways to better utilize aircraft maintenance data.
