I guess I'm too late, but if it was me I'd choose LV for carry on and Samsonite for check in. LV really is good for luggage, that's what it was made for. Although I like several of their purses, many in the fashion world mock people who wear them because they aren't about purses, they're about luggage. Anyway, for I'd be too scared to check in something that valuable and screams "Steal me" so I'd choose samsonite, they're very well made. If you like a gucci carry on that's fine too (as mentioned its cheaper and has more room or something).
