Full-fare Y is refundable by default. You can have refundable fares in lower fare buckets. The quoted price includes a premium over the Main nonrefundable fare to make it refundable. You can confirm by clicking on the fare rules. The first bullet will say "This ticket is (non)(fully )refundable as appropriate.

If you click on the last bullet "View all fare rules," you can see the fare basis and the restrictions.

Here is an example of a YVR-SEA-JFK itinerary.



YVR-SEA-JFK - Cheapest nonrefundable fares.


Fare rules shows fare is nonrefundable.


O Fare basis, refunds indicated as No.

Lets look at the same flight, but refundable!



Same route, same flight, same day but refundable.



This fare is fully refundable.



Also an O fare basis but the last character R means refundable, N mean nonrefundable.

If you clicked on refundable and offered L & K fare classes, they too are refundable and easily confirmed. You don't need to purchase a full Y fare for refundability.
