Thanks SO much @StartinSanDiego ! I am not new to FT, but I never ever post or ask for help.
I REALLY am reluctant to take ONE carry on as I will be there for two weeks and I have several functions to attend, which require more space in the bag.
I really am afraid to check in a bag for a double connection. I NEVER had a double connection...
I have tons of spinner luggages. Thanks for the suggestion.
I will read the article you suggested.
Thanks for your recommendation.
