American Airlines canceled over 300 flights Saturday and Sunday, and the reason why is up for debate.
A twitter user tweeted that agents at the Dallas/Fort Worth airport blamed a pilot strike for the flight cancellations.
But American Airlines spokespeople have been giving other explanations, citing simply a labor shortage alongside an increase in interested customers and, mostly, inclement weather.
American Airlines spokesperson Shannon Gilson appeared on CNN to address the issue.
"The first few weeks of June have brought unprecedented weather to our largest hubs [Dallas/Fort Worth International Airport and Charlotte Douglas International Airport], heavily impacting our operation and causing delays, canceled flights, and disruptions to crew member schedules and our customers' plans," Gilson told CNN on Sunday.
"That, combined with the labor shortages some of our vendors are contending with and the incredibly quick ramp up of customer demand, has led us to build in additional resilience and certainty to our operation by adjusting a fraction of our scheduled flying through mid-July."
But experts said there could be a larger reason for blaming Mother Nature rather than disgruntled pilots.
Weather provides airlines with legally-valid cover to cancel a flight without providing accommodations for travelers. Those same protections do not exist for other reasons like increased demand or labor stoppages.
