Flexible return on companion voucher?
A family member wants to climb Denali with a companion, and we have a companion voucher. The challenge is that the return date is not precisely known. Anything they choose would be more than 80% likely to change. I presume that a change would require upgrade to refundable fare plus a fee of $125 each.
If they buy a non-refundable outbound with a refundable return, will they be able to walk up to the airport whenever they want to return and catch the next flight for no extra cost? The fare rules are not completely clear on this, except that any downfare amount would be nonrefundable.
