I have AA tickets from JFK to London in late August, returning to JFK from Paris in early September. AA sent me an email saying my flights have been cancelled. When I look at the schedule, a daily flight does exist but, for some reason AA isn't selling one way coach tickets FROM Paris to NYC (tickets are being sold in PE and biz class). They are selling coach tickets TO Paris, though, and selling roundtrip coach tickets from NYC to Paris. Seems quite odd. Any ideas?

I'm trying to decide whether to call AA now to sort this out, or wait a few weeks. Right now, I could simply get a refund, which seems like a good option to have given that I've already had 3 previous trips to Europe cancelled this year and I can't say I have great confidence now that August "will work." If I somehow manage to get this rebooked, I assume I lose the ability to get a refund?
