I have a United H Class Ticket and I would like to know if it is possible to change the name on the ticket to a friend. I purchased the ticket using a Continental E-Certificate good for a free roundtrip which has since expired, but it allowed me to change the travel dates without a fee (currently booked for travel in September 2012). Since I cannot redeposit the credits back on the E-Certificate, is it possible to change the name on this type of fare with or without a fee?

Thanks!
