Have you ever seen them load an aircraft?
Pickup the case and AEG and huck it onto a trailer. Then huck it ten feet onto a conveyor belt. Then huck it another ten feet and put a bunch of other stuff on it.
Then repeat in reverse and drop it a few more times for good measure.
Look in the bag; if it's all OK then the soft case will be good to go as checked luggage.
Airsoft, where nothing is hurt but feelings.
