Airline baggage delivery folks make Amazon's janky alternative shippers like Lasership and Ontrac look like the pinnacle of German precision. Every time I deal with them, they show up randomly outside the delivery window in a clapped-out station wagon.

My impression is that wheresmysuitcase is just a central information service and the actual delivery is handled by independent contractors locally - kind of like a proto-gig economy type deal without the professionalism an operation like UberEATS injects into the mix. If they are actually employees of a central delivery service, they certainly aren't acting like it...
