Delta said Friday that it will boost hourly base pay rates by 4% for eligible ground crew employees and flight attendants.
In an internal memo, Delta CEO Ed Bastian said the raise will take effect June 1.
The carrier is also putting together a pool for merit increases, which will be based on “individual performance and market competitiveness.”
Bastian said the raise and merit pay pool together represent a $500 million investment.
“This raise is possible thanks to your solid performance and Delta’s strong foundation,” he said.
Bastian also thanked Delta workers for navigating numerous challenges in the early months of the year, including TSA staffing shortages, rising jet fuel prices, and severe weather.
