I have used a combination of buying a seat with leg room being 6' 5" and then buying upgrades or being upgraded as a Continental Platinum elite memebr ( first time as Platinum elite mainly on credit card miles). I tried to book to Asia and was told extra leg room seat are not released until 24 hours before take off. This is new to me. It is some thing that Continental has just started due to merger or did I get a bad agent on the phone?
