I've been told the answer is no by AA customer service, but often the community knows better... I bought 2 roundtrip tickets SFO-JFK for this weekend by redeeming Citi Thank You Points. My travel companion had an urgent need to be on the east coast (long story) and is already in New York, so she plans to fly back with me but miss the outbound. Normally missing the outbound would cancel the return leg, so I called to request that they make an exception (AA has done this for me in the past when it's a legitimate reason, which it is, not just trying to get around fare rules). Unfortunately because it was a third-party ticket AA will not make the change. Citi cannot change it either because it is non-refundable. The best option I've been given is purchasing a new one-way ticket back (at more than the cost of the original roundtrip!), forfeiting the existing ticket completely. Anything at all I can do???
