2hrs is definitely plenty of time. However, coming from LHR, I would be extremely cautious. Flights to/from LHR are notoriously late with the congestion of this airport and so...Even 1hr will be more than enough but involve much more stress.
Satellite questions for you:
- will you have checked bags
- do you have any status in a Skyteam FFP or do you travel in business or premium eco class ?
