I don't get this? I'm tall and fly AF out of T2 often, but never early morning! The only thing I hate about T2 is the overcrowding and no decent food. But I usually just head for the AF lounge.

As for transiting LHR, I actually like it. When I used to fly BA monthly LAX-LHR-NCE I got used to the bus and quite enjoyed the shopping and the BA F or Concorde lounge. Later when they added the MB Spa it was great! I've transited LHR well over 100 times over the last several years and I've never had a significant problem other than one very long security queue during a holiday period. Now I know to avoid LHR when the holiday masses are coming or going. I only did the GTW-LHR transfer once and hired a taxi for that. It was expensive, but worth it to me.

I guess there is one thing I REALLY hate about LHR and that is how long it takes to drive there (with or without the M25/T5 construction), return my Avis car and take the bus to the terminal. It's about 5 times as long as doing the same at most other airports including LAX.
