At that derisory level of offer I doubt anybody would bite.They needed to start at 2K and go up from there.
I just took a vdb offer from American.They started at $300 and went up to $800 where I agreed.But I only swapped a SJU-MIA-LAX-HNL in F for a SJU-JFK-LAX-HNL in F,which got me in a little later.
Expecting anybody to accept an offer like that for a downgrade from CW to Y is just devoid of all reality.
