The month of May saw an increase of flight cancellations as well as passenger complaints. The rise in cancellations by airlines may be due to the avoidance of new rules to fine airlines that strand fliers on delayed flights for more than three hours.

After one of the hardest times in decades, the U.S. airline industry is starting to see demand increase, fares rise gradually and planes fly at closer to capacity.

Recent statistics from the Transport Department show flight cancellations increased in May by approximately 30% from the same month last year, while customer complaints against U.S. airlines rose 23%.

The report also proved that the number of paying passengers denied seats on flights rose 37% for the first three months of the year.
