I'm looking at flight in business on Ukraine International because of a very attractive fair. I'm aware that it is not a great business class and they use old planes with old style business class seating.
I want to purchase the ticket to lock in the price. But I want to keep looking for a good price or late award availability on a more preferable airline.

The fare rules seem to indicate that it is refundable, but the screen where all the available fares are listed shows an X for all fare types under the refund column, but show a check for all of them in the change column. I am doing a one way ticket.

Here are the fare rules regarding cancellation/change. Can I cancel a one-way fare?
