Both 12/17 and 1/7 CSG-ATL was delayed due to MX, they put us on a bus instead of flying. Ended up 3 hours late on 12/17 and 5 hours late on 1/7, missing work both times.
Got a $200 voucher upon complaint about both events. Others on the bus got 10,000 miles for one event or 20,000 miles for both. Of course got the Original Routing Credit as well.
(The second time I was rebooked into J for ATL-DTW which made the delay worth it!)
