The confusion of the sudden cancellation turned to anger after hundreds were left stranded, and upset passengers began to fight near the crowded Spirit Airlines check-in counter Monday night.

According to Spirit Airlines, the flights were cancelled due to a breakdown in labor negotiations. Spirit is claiming the pilots are refusing to fly to influence the outcome.

The carrier, which says it has canceled more than 150 flights in the last two days, is now asking a court to intervene with the pilots union – and its customers appear to be caught in the middle.
