2nd hand info but a lot of people I've talked to have had numerous delays during training, regularly up to 6 months total during the course of waiting. L3 are trying to reduce delays, but still taking large intakes of new cadets regularly when the training pipeline is bursting.
I'd say if you can get in on a scheme tagged to an airline, go for it. If not, CAE might be a better option.
Cash flow isn't an issue for L3, it's a gigantic company with deep pockets and they are investing heavily since taking over CTC, ramping up training all over the place.
It was actually the flight school side of CTC that L3 wanted. They had sim centres all over the place, but wanted to be able to offer everything from first flight all the way to airline level. Let's hope things eventually settle.
