That is close. Here are the exact numbers as of about 3 weeks ago.

Here is the latest retirement schedule. Subject to change of course.
2014- 14 757
2015- 15 757
2016- 13 757
2017- 22 757 4-767

Over the next 4 years we lose 64 757 and 4 767 airframes. In addition we retired 16 757 airframes in 2013. No other aircraft types were listed for retirement. We should gain around 205 airframes over that period. Net gain 135 plus airframes.

There is a chance 10 of those airframes could stay depending on a charter contract.
