Apparently it's more of a Europe thing. Most major low costs in Europe like Ryanair/EasyJet/Norwegian/Wizz Air don't have ID/ZED agreements with other airlines. The only exceptions I remember are Germanwings and Vueling, but because they're part of Lufthansa Group and IAG respectively.
But if you think on a worldwide perspective there are quite someLCC with ID/ZED available.
Canada: WestJet
USA: Southwest, JetBlue, Frontier
South America: GOL, SkyAirline
Asia/Oceania: Jetstar, Flydubai, Tigerair
