Add me to the list of complainers on how DL does with baggage.
We returned on from an international flight and missed our connection by 10 minutes. Our bags (tagged priority) were the last ones off the plane (15 minutes after they started coming off).
We were booked on another flight 3 hours later BUT our bags STILL did not make the later flight.
DL offered no explaination or reason why they couldn't find the time to move our bags to the later flight. Bags did arrive the next day.
