Yes, a couple weeks ago going to Vienna my airline was oversold and with 1 flight I wasn't trying us so I ventured to Lufthansa because they had three flights which I checked on my system and they looked good so I listed myself in business. I went to the airport gave them the ticket at JFK and was given business to and from with no problems. Only thing though is I wanted to take the 747 but I didn't want to wait around because as a non-rev always go for the 1st flight.
