Delta Air Lines apologized Thursday after a husband and wife from California claimed they were kicked off a flight last month with two of their children once they refused to give up a seat they bought for another child.

Brian Schear, his wife, and two of their children, were reportedly boarding a flight from Maui, Hawaii, to Los Angeles on April 23 when airline officials asked the couple to give up a seat Schear says he had purchased for their older son.
