Use the tough plastic sleeves attached to our Luggage, also have always carried on changes of clothes, on Ship and Airline, just in case. Then traveling with someone Wife, Kid, would split clothes up, half in each bag. Started this when one our Bags was flown to different State, arriving 24hrs later to our Port Hotel. Finally, last 20yrs have arrived at Port 2 days early. Seen too many miss Ship due to Weather, Flights Delayed/Canceled, or car issues. Fly 12-14 times a year and see this happen more last yr then have in my 40yrs of traveling
