You said what I was thinking (about CO), MF.

The question is - do you want or need the miles? If you already have zillions, that's unlikely. Who are you going to take your free trips with anyway? (would you rather fly BA then?)

(US) BA golds get 100% bonus miles, & you'd get the 50% first class bonus too. Or do they deny the bonuses to UK-based premier card holders?? (I suppose if you've paid APEX-rate economy & travelled in first...)

If I were flying to the West Coast I'd go with BA's comfort & service. The shorter trip to the East Coast might be okay on one of the other airlines: it's no great hardship to sit in a Club-style seat for six hours, as long as you don't get a 'red-eye' type flight.
