I have a ticket on United (Economy "K" class) for a 2-week trip in January from Canada to the US. The ticket is non-refundable, but is changeable for a hefty fee ($200) and is valid for a year. The ticket is also marked "0VALUAFTDPT - Cancel reservations before the scheduled departure time or TICKET HAS NO VALUE"
Let's say I can't travel in January, and instead I want to take the same trip sometime in the summer.
Now, if I knew my exact travel dates in the summer, I could just pay the $200 fee (and any difference in airfare), and make the change.
However, what if I don't know my summer travel dates yet, and won't know them by my original January departure date? Is it possible to cancel the January reservation now, and pick a new travel date much later, paying the $200 change fee only once? I.e. can I "park" or "store" the value of the ticket without picking a new date right away?
