Southwest Airlines says it expects to resume normal service this week after cancelling more than 2,200 scheduled flights since Saturday, blaming unfavorable weather and air traffic issues in Florida.
The airline had cancelled 1,124 flights, or 30 per cent of its daily operation, on Sunday and more than 800 trips on Saturday.
Flight tracking platform flightaware.com. showed another 360 cancellations on Monday.
In a message to staff, Southwest Chief Operating Officer Mike Van de Ven said the sudden flight cancellations had caused staff shortages and may lead to a reduction in the number of flights the company can operate in November and December.
