Airlines Have Been Staffing Up, Hoping for a Smoother Summer https://www.wsj.com/articles/airlines-have-been-staffing-up-hoping-for-a-smoother-summer-11649583003

Facing a summer of packed flights, airlines are striving to avoid the blunders of a year earlier.
Carriers say they are taking seriously the lessons of last summer when operations were strained due to booming demand. With staffing thin, many airlines were unable to recover quickly from what should have been routine disruptions such as poor weather. Travelers faced cancellations, delays, and hours-long waits for customer service help by phone.
The war in Ukraine, soaring jet fuel prices, new Covid-19 variants, and a blistering labor market all loom large on the airline agenda for summer.
