Hi everyone, I don't know if this is covered earlier. I used my CO miles to ticket a FC DL flight from MSY to LAX. I think I want to get on a CO flight earlier in the day. Do you think I can same-day confirm for 25 bucks (i'm gold elite for CO) or even same-day standby for the earlier flight?

I called CO today and they said that I will need to shell out more miles! Is this true?
Thanks!
