Retirement age for pilots

The news reports indicate that there cannot be 2 pilots over 60 in the cockpit. That will be a huge problem for LCC. I am sure they will have to hire a ton of reserve f/os to sit around and replace the age 60 f/os on trips (replaced at full pay) and think of the International flights with 3 pilots, all of which are likely to be over 60, two replacement f/os will be in order. I am betting a buyout will have to be the rage of the day. How many pilots will be on full disability after age 60...I bet that skyrockets. I think economically, this will be a disaster for LCC.
