That occurred to me after I posted my reply, its conformance not checkin close that they are referring to. To be honest I can't understand why a time focused exec would risk getting to LHR security after -35. Assuming that their company requires them to travel for a reasonably important reason it would be remiss to risk missing a flight by arriving later than that time.
