There is a ton of non-bidders NB for various reasons ie. medical which results in the 1350. That number was derived from adding up the active bidders in the bid packets. The company is short staffed at the moment. If attrition somehow grinds to 0 in the summer, it will still be appropriately staffed for the reduction in flying. The hiring presumably is to maintain the current pilot count assuming attrition continues at any rate.
