American Airlines is apologizing to its best customers for the recent increase in delayed and canceled flights.
The airline sent email messages Friday to members of its AAdvantage loyalty program saying it was sorry for the inconvenience.
AAdvantage president Suzanne L. Rubin said the airline stands ready to help customers. American blames an increase in delays and cancellations on a surge of maintenance requests filed by crews and by an uptick in pilots calling in sick. The pilots union said there is no organized sickout or slowdown.
