DALLAS (AP) — Travelers who counted on Southwest Airlines to get them home suffered another wave of canceled flights Wednesday, and pressure grew on the federal government to help customers get reimbursed for unexpected expenses they incurred because of the airline’s meltdown. Exhausted Southwest travelers tried finding seats on other airlines or renting cars to get to their destination, but many remained stranded. The airline’s CEO said it could be next week before the flight schedule returns to normal.
