This will only work If you're booked in economy on this flight
I'm currently ticketed in Biz on this flight and don't mind sitting in economy
I am offering my seat for $1200 OBO.
The process is simple, both of us will check in using our original tickets, once we board we change seats.
If you need the extra luggage we can work that out as well.
PS I have posted about this offer in the past, being that this is for a different flight I started a new thread.
