The liberal rules re. free domestic stopover for an international award ticket may be changing. This reviews a leg recently added, thanks those on TOBB who went before and graciously shared their knowledge and alerts those who come after of some pitfalls and how to avoid and that this may change soon. My original, booked, award trip in Feb was New Orleans to Rome. The trip was a plain vanilla round trip: MSY...FCO (in Dom. F, C) FCO...iah...MSY (in C, Dom F) After reading this thread, realized that a leg to ANC (Anchorage) perhaps could be added. Confirmed, by making a dummy booking - on .bomb, that adding a 3rd leg months later did not change the 100 K miles required. The addition in May: MSY...clt...ANC (in dom. F) First attempt: On-line - afraid to touch an already booked C TATL - gave up Second attempt - call to the "Premier Line" got an intl call center agent, who didn't think this was possible and made it clear he didn't want to check. Asked him to please check if his computer would price it out, so I could see cost and availability, mentioned I'd just been able to price it out on ua.com. He did and confirmed that no more miles would be required, but he thought that just wasn't right, it was like a free one way. He decided to check with his supervisor - long wait - then came back and said you can't do that. Said thanks, and hung up. Third attempt - call to "Premier Line" actually got a US agent, who cordially agreed to check on this - the computer let her price it out - same # of miles as the original 2 leg trip, $25 change fee per person and trivial taxes. (the miles didn't come from my mile bucket, hence the change fee) The new reservation now covers Feb: MSY...FCO Feb: FCO...MSY May: MSY...ANC PRACTICE POINTERS: This is best done when making the original reservation - you never have to talk to a person. If you've already made a reservation and want to add a leg, check availability for the proposed new leg on .bomb, price the miles out and availability there, then call UA. If the first agent(s) proves difficult (in my case, the system would allow it, but I was put on hold so his supervisor could make up rules and override it and deny the change!), fume silently, thank profusely and hang up. (You don't want nasty notes being put in your record). Call, repeat as necessary. Per the original, first and difficult agent, this glitch in the system probably will be "fixed" (w/ Unix programmers?) so that it will no longer possible to generate a new leg like this. If you have any Intl award travel pending, now is the time to think about adding a new leg! This may have been a rogue agent or ??? but for any help it may be, his comment is repeated here.
