We just (Aug 20) had a 65 minute connection for DFW-FRA/FRA-TLL on Lufthansa. We used the 90 Euro gate connection which worked very well. Were met at the B gate by a gentleman holding our name who put us in a cart and got us first through passport control (bypassing LONG lines) and then through security and to our A gate. Both gates had changed from what was originally scheduled. Well worth the money to avoid the hassle and possible missed connection.
