New solo consulting business where I have to do engineering surveys on-site, any hacks for traveling with 2-3 small to medium pelican cases? My main concern is losing them or theft.

I know I can always check them in but that means I will be dragging them around at airports, I considered shipping ahead of time but it can very expensive pensive since I usually have several hops during the week and would need to do overnight shipping which also take time if you need to drop them off at FedEx/UPS stores.
