The problem isn't just getting TO COZ. Our flight home was delayed by thunderstorms, and we got into MIA late, missed the connection, and the next flight wasn't until the morning. AA said "we don't reimburse for weather", and gave us voucher so the hotel room cost "only" $100 and a lot of stress. Next time I'll consider a bag drag.
Yes, usually my problem with connecting flights was in the US return.
