I line my Aviator bags with large trash bags (bin liners) put everything I want inside the bag in the bag, close the trash bag, zip up the Aviator & go fly.

The trash bag (bin liner) keeps everything nice and dry while the loading and unloading process is going on.

I use the same technique with many other sorts of luggage for the same reasons.

Thanks for the guy the other day who moved his own bag out of a first class overhead bin to give me room for my Sun Chaser bag. The airplane was overloaded with carry on bags.

A real classy guy!
