135 operations: You are not allowed to even manipulate the flight controls unless you work for that carrier and is current and qualified in that specific aircraft. A training flight (logable) will be Part 91, followed by the 135 proficiency check and line check. After that, a company check airman will most likely fly with you: If you received a 135 SIC ride, then log SIC. If it was a 135 PIC ride, then log PIC.
Part 91 operations: Log whatever you want. It is your logbook but don't be surprised if asked to justify (by the FAA or its representative) how your flight time can be used towards a certificate or rating and/or currency.
