Thanks. I fly to Europe 2 or 3 times a year biz class out of dulles. I often end up stopping in the uk. I switched from united to BA because I can't bear the idea of the newish United biz class four middle seats. I also prefer changing at heathrow T5 instead of Frankfurt. I also like the sleeper service when it is actually available. United has a late night flight too but they clatter dinner and drinks so it's hard to sleep.
