Airlines are responding to high sickout numbers during the pandemic by trimming their schedules. Alaska Airlines said Thursday that it will cut its schedule by about 10% for the rest of January. The move comes as nationwide flight cancellations top 2,100, the 12th straight day above 1,000. Seattle-based Alaska Airlines says it’s dealing with an unprecedented number of employees calling in sick as COVID-19 cases surge nationwide. Alaska’s move is similar to a decision last week by JetBlue Airways. Other airlines, including United, are offering bonus pay to find employees willing to work extra days.
