It depends on the FA
on whether or not they want to be prepared for the "just in case" scenarios.
's who fly turns regularly tend to just bring their turn bags...usually a small roller tote. They carry the bare minimum- manual, company required items, food, etc.
's, especially those who know all too well from being stranded in other cities- even though they were doing just turns, pack a roller bag at the least. It's not too difficult to roll around a roller bag on your trips just in case your trip ends up being extended unexpectedly. It would be nice to be able to have just a small and light tote bag to bring everyday if you were doing just turns, but I'd rather be safe just in case.
Those of us in the industry know very well how things don't always go as planned. Weather is a big item in changing the plans of an airline's daily operation. It depends on whether or not one would like to have a few changes of clothes, undergarments, toiletries, running shoes, swim trunks/swimsuit, etc. should they be stranded some where.
Cheers and safe flying!
