Hello Paul
Just saw your post.
I also have the Scicon AeroComfort bike bag.
One challenge you’ll encounter is the strong likelihood that the baggage handlers will flip the bag on its side (as opposed to keeping it vertical) and place other luggage on top of the bag when stowing it on the plane.
In regards to the above, one preventative approach you can take to minimise excessive pressure being placed on your wheels (in particular the spokes) is to insert a protective profile/template into the wheel sleeve within the Scicon bag. They are quite easy to make (I used 3mm ply, cut it into the profile of the wheel and placed a 25 mm hole in the middle of the template) – this ensures the template (x2) centres on the wheels hub and doesn’t move when in transit. I now leave the template in the bag ready for the next trip.
Cheers
Simon
