"The continuing aircraft deliveries require staffing increases on the fleet. Between now and the summer of 2016, we expect to add approximately 13 incremental aircraft, training will therefore need to continue at maximum or near maximum capacity, with a significant portion of training at off-site locations.

Our new-hire plan totals roughly 1,600 pilots over the next 18 months, spread across our 737and 320 fleets.

Given our 737 fleet is still not balanced, the upcoming vacancies will serve three purposes: rebalancing the fleet, funding new hires, and continuing the regular staffing process. To that extent, we will continue modest growth in DCA, along with SFO, ORD, and LAX. IAH will reduce in size, as previously announced."
