Runways are named by a number between 01 and 36, which is generally the magnetic azimuth of the runway's heading in decadegrees. This heading differs from true north by the local magnetic declination. A runway numbered 09 points east (90°), runway 18 is south (180°), runway 27 points west (270°) and runway 36 points to the north (360° rather than 0°).[2] When taking off from or landing on runway 09, a plane would be heading 90° (east).

It doesn't have to be a 180 degree flip, it could just rotate any number of degrees. I think I read somewhere is the most likely orientation of the new poles will be at 90 degree angles to the existing polar orientation.

Because there is no stress transfer between the core and the mantel, the core is a fluid. It would have to be a solid to translate forces to the mantel in order to make the earth change it's orbital orientation and it would have to be a huge force to overcome the angular momentum of the earth due to the rotation of the mantel and surface/crust

I’ve been hearing about this poll shift thing for fourty years now. Through enough crap against the wall.....,,,,

The poles switching (i.e., positive and negative) doesn't seem like it would be much of a big deal as long as it happens quickly. The scarier scenario is where the poles actually drift from where they are today. That, I would guess, has a lot more consequences on the weather and the planet under the surface.
