I would think they might work with you under these circumstances, but it might take a series of calls and long holds to get someone to make it happen. If you're a Rapid Rewards member, try to find a phone # for RR help, I have found that I've been able to get through quicker through them, and they seem like they are maybe a little more able to make decisions and exceptions.
Best of luck!
We have a trip planned for 4/10-4/18...just playing the waiting game at this point!
