The deliveries are 15 per year over 3 years. There has been a substantial change in the overall fleet plan since last spring. If you have Delta net there is a discussion about it under the SEA roadshows. The shift of DCI block hours to the mainline is coming to a end this winter. With the TA it was planned to continue that migration which would have required more pilots. The Skywest E175 order is the start of managements plan B.
The good news is even without the additional block hours hiring should be strong.
