I'm new to flyer talk. Actually just found it today. Seem's like a great forum.

I have a flight booked for Friday night from IAH to EWR. I'd like to change it to Thursday night. I called CO and they said it would be $150 change fee (which i understand) then another $900 for the new ticket. Is this for real? I purchased the ticket months ago for $390. Any suggestions? U think it would be the same deal to just move to an earlier flight on Friday?

Thanks,
JD
