This seems like an extremely basic question, yet after quite some research the only relevant info I found was that I should have saved a PDF of the fare terms provided only once during the reservation process.
Through a Google Flights alert I found that the multi-stop ticket I bought a few weeks ago on united.com is now available at a lower price, and while I strongly suspect that the fare I bought is non-refundable (at least not fully; due to its already quite low price), I would like to make sure that I indeed wouldn't save money cancelling the ticket and then buying it again.
On the cancellation page, the sum I paid for the ticket is displayed in green as "reservation value", above "credit towards" options for what one could assume might possibly be a refund. Conspicuously absent is a clear indication that any of this does in fact guarantee a refund of the sum displayed – is there any way to find out in advance if my ticket can be refunded, and if so, what the penalty would be?
