FORT WORTH, Texas — Airline stocks rose Monday, spurred by signs that vaccine rollouts could set up a rebound in travel later this year.

American Airlines, meanwhile, announced plans to raise $7.5 billion by borrowing against its frequent-flyer program and using the funds to pay off a federal loan that it received nearly a year ago, in the early days of the pandemic. The airline said the actions won't increase its overall debt. It follows similar moves by Delta Air Lines and United Airlines.

Airlines have been particularly hard hit by the pandemic, and travel restrictions continue to eliminate most international flying. After a dismal January, the number of passengers has since trended upward. On Sunday, the Transportation Security Administration screened nearly 1.3 million people at U.S. airports. While that was down 41% from the comparable day in pre-pandemic 2019, it was better than the 58% average decline this year compared with 2019.
