last year United (the airline) made a mess with my flight and I got a $100 USD coupon for another flight ticket.
I can't use it before it expires (21st July 2018) and it's not allowed to sell it.
So someone interested to book a flight on United website?
In that case I could offer a free coupon to be used with flight.
To get this straight, I don't like United much and I would be disappointed if the coupon expires unused.
If someone is interested to book a flight, answer and I can give the scans of the coupon papers to you. Book something and if it works, be happy.
