It's a pretty polarizing subject. I am in the "just check all my crap and be done with it" camp, but many people you'll have to pry their roller bag carry ons from their cold dead hands.
After landing, instead of just up and leaving the airport, you gotta go to your baggage claim and wait for your flight to get processed. Sometimes it easily adds over an extra hour to the experience (and even the best case scenarios still take me about 30-40 mins extra at least, and that’s domestic flights).
