The wait list probably isn't mentioned because it is very fluid. Airlines book spaces on certain course start dates but if they don't fill those places then they become available to others. Similarly, it's surprising how many people are assessed and pass assessment without realising the cost, or the full commitment required for flight training so they are given a start date and then pull out. Also those that manage everything well may have problems securing the money or their medical before the start date, so they're shifted back and others shifted forward.
For these reasons the wait could be 2 months to 8/10 but is unlikely to be the full length of time. Right now though there are a lot of airlines booking places for their cadets so self sponsored places are limited.
