Delta's offer also includes a lump-sum one-time payment, reduced health insurance premiums, and improvements in holiday pay, vacation, company contributions to 401(k) and work rules. Its union estimates the proposed deal represents more than $7.2 billion of cumulative value increases over the next four years. Similarly, United pilots turned down an offer that included more than 14.5% cumulative wage increases and enhanced overtime and training pay. Analysts at Jefferies estimate Delta's offer could hike non-fuel operating costs by 450 basis points in 2023 vis-à-vis 2019. Casey Murray, a pilot and the president of the Southwest Airlines Pilots Association, said Delta's proposed deal will help it in the competition for a shrinking pool of pilots.
