OTOH since this is becoming a Cathay-everywhere thread I might again mention that Cathay told me a couple of months ago that they will no longer do xONEx reissues at LAX. SFO and Vancouver were the choices they offered me. I'd guess they'd accommodate a traveler with an immediate problem - my request was for travel some weeks ahead. I ended up letting AA do it. It was painful as usual, but most of the pain was borne by the Aagent at ONT who no doubt was having her very first experience with such a ticket. All I had to do was stand around for a couple of hours feeling sorry for her.
