Alaska Airlines charges cancellation fees based on the ticket type and time of cancellation. Refundable tickets typically don't incur fees, but non-refundable tickets can be subject to a fee. You may also be eligible for a flight credit rather than a refund. For more details, call 1-888-394-9616. https://mysupport.commscope.com/forums/general-discussion/b183d0d1-bfc1-ef11-95f5-6045bdb3316f
