I wish I could give you a comparison. My husband and I are booked on the A350-1000 daytime flight in June, JFK to LHR, . I deliberately chose it because I find it really difficult arriving in Europe in the morning after an overnight flight. I just can't shake off that feeling of exhaustion. A younger me could tolerate it. But now that we're both old, the idea of arriving in London at 8 pm and being able to go straight to bed once we check into our hotel is really appealing.

But to get this flight, we're staying at the TWA hotel the evening before our flight, since our departure city of Boston had a very tight connection to the morning flight and I didn't want to risk missing the flight and being stuck with the overnight one.

I've been searching for reviews of this particular flight and haven't found any so far. Since I can't, I intend to write one of my own.
