It's not totally safe to assume that cancellation a year from now will result in a UA credit rather than an expired Capital One travel credit.
I mean, my experience is it does. YMMV, I guess. Worst case, if online cancelation won’t give an FFC, one could call and have Ua do an official ‘takeover’ of the ticket ($50 fee, I think), then get the credit to stay there.
my main point was it doesn’t matter if you cancel today, in a month, or in 9 months from now. Resulting credit will have the same expiry - 1 year from date of issue. And there is no reason to wait to cancel if the sole purpose of booking was to simply use the credit (unless one is waiting for a schedule change so they might be able to get a full refund, but in this case, doesn’t seem wise as the agency booking will definitely be an issue - especially with credit use, but also given the funds will have to go back to Cap1 and presumably eventually back to customer, and in the case of the credit, likely will lose it if expired anyway).
I also am pretty confused about folks who have this card but can’t seem to find a way to use this credit for some sort of actually planned travel in the span of a year, and so are looking for a way to ‘game’ the credit. We travel much less than we used to (thanks to kids…and stuff), and may not even hit any level of premier status on UA this year for the first time in probably 15+ years - still can easily use the credit. This year, we did end up having to cancel the trip we had used this for - but that was last minute due to kids getting sick. Why pay a $395 fee for a card where probably the biggest benefit is the $300 credit if you can’t naturally use it? Wouldn’t a regular Venture card be better in that case?
