I had always thought that UA let you mkae a stopover on domestic reward tickets. After trying to make a reservation last night I was informed only Hawaii awards allow a stopover. Reading over ual.com confirmed this. Is this new? I guess my AA miles are now worth more to me. Would have also liked to use a DL award for stopover in CVG. DL miles allow this, but using UA miles doesn't. Too bad I don't have any DL miles.
