She has diabetes. His mother had diabetes. It turns out his flight was delayed last night because one of the flight attendants went into a diabetic coma. They had to stop in Atlanta, and Spirit doesn't fly to Atlanta. Then they had to find a replacement crew member who happened to be in the area on Easter Sunday.
One Easter when they went to Florida it turned out their Monday tickets home were actually Sunday tickets. And the flight was full. And the next flight was full. And the next flight was full, and so on, and so forth. They ended up taking a flight to Atlanta, where they were told there was a better chance of getting a flight to New York.
His mother was alive then.
