The nationwide issues of cancelations with Spirit Airlines are also impacting some flights in and out of Las Vegas.
A labor dispute with pilots led to cancelations across the country Monday, with a viral video in Florida even showing a brawl with frustrated customers.
At McCarran, officials say 5 or 6 flights were canceled Tuesday, and there may be another 5 or 6 tomorrow.
They say, though, most of the the customers impacted by those cancelations were notified by email ahead of tie, so they don't have to show up at the airport and can make other arrangements.
McCarran says Spirit is working with customers to rebook them on other airlines or provide hotel vouchers if needed.
