our return trip LHR-PHX was a disaster, we got stuck in the weather in Europe. Granted it was BA fault but luckly I had 3 weeks off so being stuck for an extra 6 days in London wasn't a problem. Getting flights out was a mess, having friends in London meant not paying for a hotel. So with that, our flight LHR - PHX was interesting, when I checked in was offered $250 WT to WT+ which I jumped on it having a great fly to LHR in WT+ the added room was nice. At the airport was offered $450 WT+ to WC, jumped on that. All I have to say is WOW. We flew UA IAD-CDG in J, wasn't all that impressed, but this flight was excellent. Sat in row 63 AB. Well worth the $700 total upgrade...
