Bikes on planes....

I remember an airline requesting that I deflate the tyres on my bike when I took it on a long haul flight. Makes sense, because of the air pressure.
My question is this:
I am intending to buy a bike with air sprung Rockshox forks. Do I need to deflate the forks? Is it easy to do? Is there any risk of damage to the forks if I do this? This is very important as we will have over 1500 miles in front of us.....
Thanks for any answers from anyone who may have taken a flight with air sprung forks!!!

No, it doesn't make sense. The air pressure inside the plane never drops below that found at an elevation of 8000' and people riding up a mountain to that altitude don't bother to drop the pressure in their tires (or forks) by a few psi to compensate.

Even if the plane went into space and the pressurization system failed it would only raise the effective tire & fork pressure by less than 15 psi - well within the safety margin.

That's because one bar (1000 millibars) is normal atmospheric pressure at sea level and is only 14.7 psi.

As others have stated, no.

I didn't bother to deflate my tires last trip, no adverse affects, I'm just ignoring the advice in the future. One of the guy I traveled with had air shocks, likewise no issues flying trans-Atlantic.

Thanks guys.

Well, that's very small weight off my shoulders. Thanks one and all

Just one little thing: I flew my bike to and from Hawaii last April. On the way there, all was fine, but after the way back, my hydraulic brakes were "stuck" for a while. I brought it up to my LBS, a day later, but they told me it came back fine on its own within a day.

Not sure if it's common, and I'm not sure if it's something which can result in the brakes needing a full bleeding, but I thought I'd mention it just in case.
