There used to be an issue where if you searched for reward flights more than two months ahead it wouldn't display any results, but actually you could get around this by choosing a date within two months and then once in the flight list screen just advance the date until you got to the one you wanted. That issue seems to be fixed now and you can search and get results for flights more than two months ahead - I have just tried to check it works.
