Thanks for all this. Quick thoughts:
- I live in London now, so awards would be preferably based from here - I don't know if that removes the possibility of interesting redemptions?
- I've been able to use TSA Pre on most of my US-UK flights, not just domestically in the US, but this is definitely a minor point.
- if I flew AA LHR-ORD, I don't think there's any premium economy? I really don't want to fly with standard economy seat pitches. Also I guess the earning would be 1x miles, rather than 1.5x.
