DETROIT — The worries are growing for United Airlines flight attendant Jordy Comeaux.

In a few days, he’ll be among roughly 40,000 airline workers whose jobs are likely to evaporate in an industry decimated by the coronavirus pandemic.

“I don’t have enough, unfortunately, to get by,” said Comeaux, 31, who has worked for United for four years. “No one knows what’s going to come next and how to prepare.”

It all runs out on Thursday.

With air travel down about 70% from last year, many carriers including United and American say they’ll be forced to cut jobs without additional aid. Delta and Southwest, two other big carriers, tapped private capital markets and say they’ll avoid layoffs.
