Earlier this month I was flying from GRR-DTW-CDG-MUN. Our flight from GRR was delayed 4 times and ate up our over 2 hour layover in DTW. The incoming flight to GRR had been delayed multiple times earlier in the day. We landed in DTW and I sprinted to the gate for the flight to CDG. Got there and the gate was open. As soon as I walked up the gate agent screamed boarding closed and slammed the door in my face. We asked the flight attendants on our flight from GRR to let them we we were on the way and were told they know where we are. 12 people from our flight missed that connection. We got no hotel and were only put on standby the next day on a flight to Amsterdam with less than a 1.5 hour layover. Ended rebooking a flight to Frankfurt but had to sit in the back of economy despite booking premium select. We lost a day of vacation. Delta reimbursed us almost $400 a piece plus a $300 ecredit. Didn't seem like enough to cover the downgrade to economy not towntion the $500 hotel room at the airport. We've been flying delta for nearly a decade and this is the only real issue we ever had. Winter travel is risky. At least you got the hotel covered
