I know someone who called United about one of his 5 tickets that deducted miles for one passenger (2 passenger itinerary), the eticket receipt said it costed 8 miles but the full price of one passenger was deducted from his account. After one perplexed agent transferred him to a supervisor he was told to call back tomorrow and told that all such tickets will be voided as it makes no sense for such a ticket to only be 8 miles.
Otherwise, I'm happy I got myslef 3 JFK-HKG roundtrips in FN but regret I didn't take advantage of this more, maybe an Israel trip? Oh well!
On the one hand, I expect United to honor these but on the other hand I'm not holding my breath! I guess we'll just wait and see!
