Another plug for those that have completed the written, have the mins and just need to take the practical (check ride).
Do not wait until the last month or two (June/July 2016).
It's impossible to guess how many of the 20,000+ folks that took the written in 2014 that will end up taking the check ride. But, the ATP written prior to the rule change was 3-5,000 annually.
I worked at a flight school that had people calling from Hawaii trying to find open test time to take the written.
I guarantee the capacity to administer FAA written exams far exceeds the capacity of flight schools and DE's that can give the ATP check ride.
Don't procrastinate only to find folks booked up. That would be a very costly mistake if you all you needed was the check ride.
