Excellent. Keep investing in changing these policies instead of improving your broken airline and IT.

I suspect RM is doing this because a lot of people will book those terrible early am flights as they are cheaper and then switching to later flights. There is also quite an advantage to doing this because if you are booked at say, 6am on Tuesday, you can SDC up until 1159pm on Tuesday but you can call as early as 6am on Monday. Essentially way ahead of anyone else and up to 36 hours ahead. Not anymore!
