I don't known if this is really the right thread, but here goes...

I had some Avios that I wanted to give to a friend. I knew they were approaching expiration as I now credit to JL, and it was too little to really be useful. When I logged in to transfer them, the had expired yesterday. Is there normally a warning sent that you have Avios about to expire? My account statement beginning of April had no warning.
They put in a request to reinstate, is that likely to happen?
