Be very careful with OAS. Their twin was unserviceable since April or May until a week or so ago, and after they let their ATPL students fly it a couple of times, they canceled one of their training days for the Chief Flight Instructor to take it on a personal trip. It then went mechanical again.
With the job market the way it is, a 4+ month delay on training is absolutely unacceptable and is costing these students job opportunities.
