Y Class

Y class is the class for a full-fare coach class ticket. A Y class ticket is the most expensive ticket in the coach cabin, however it also offers the most flexibility: free date changes and fully refundable. In most cases, however, it does not make sense to purchase a Y class ticket, as the fare difference is far more than any change or cancellation fees would be. "Y" is also used as a generic term for all coach class seats, as in "I'm seated in the Y cabin."
