Hullo pinkcat,
Sorry I cannot answer your question - I hope another FT'er can - but it seems like you might be able to answer mine. I'm looking at having to make a 24h trip to PHL in March. The flights I am looking at the late-night 767's.
What's so much better about them than the 777's? I don't think I've ever been in a BA 767! Any recommendations for the best seats?
best wishes
