Next aircraft is due out of bridging maintenance in December, with the following aircraft beginning bridging towards the end of 1Q19. They found a lot of stuff needing work on the first aircraft which delayed its delivery and pushed the second aircraft back. The other 4 aircraft that were purchased are in a leaseback arrangement with the original operator. What the plans for them after that lease is over is unclear at the moment. It all depends on the market.
Applications are currently being accepted for a 21 August class. Not sure if there will be another class to follow later this year, but I know it is being discussed.
