The higher cabin pressure of the 787 is amazing, though. I suppose if you're extra-tall it makes sense to avoid (or at least to check the seat configuration), but otherwise they're lovely aircraft.
The higher cabin pressure is happening on all recent (large) aircraft designs. It is a result of using more composite materials and humidity control. None of that matters when the seat is smaller than you are though!
I've taken a couple of flights on the 787 and I would swear it makes a big difference. (Or am I just "placebo effect"ing myself?)
Its definitely a big difference. On a 12 hour flight to south america it was far more comfortable than any other similarly long flight I have taken.
Its a big difference, basically the same as being at Lake Tahoe vs. Mammoth Lakes (if you happen to have been to these mountain places in California).
