Scott,

I think this should be the number 1 issue Boeing exploits. On a typical plane I and 1000s of other people get dried out, get headaches (especially the kids) on landing due to cabin pressure changes and can never see out of the windows very well.

Imagine for a moment that the prices are the same for either flight. People will get a chance to fly both flights. If the cabin pressure and humidity make that much of a difference, which I believe they will, let me ask you this.

Would you prefer the plane with or without the babies yelling due to cabin pressure and humidity differences?

Would you prefer the plane that has bigger windows that you can see out of?

Would you prefer to arrive feeling fresher (more humidity, more pressure) and less tired or not?

Now, what you should be asking is, what does an Airline do with its A350s once passengers have flown on a 787? How much of a discount does it give and is it worth it to the passengers?

All I know is if the pressure and humidity claims are true about the 787 I will refuse to fly any other plane whenever I travel and will fly the airline that offers me a 787 to the destination I want to go.
