We got tickets for my 17 year old daughter to travel from New Orleans to Birmingham and back (departures on 4/8 & 4/15 .) The ride from New Orleans to Birmingham had little issues and arrived about an hour late.
There were significant issues with her return trip from Birmingham to New Orleans. The departure time from Birmingham was abut 2 1/2 hours late, so we knew her arrival would be delayed. There continued to be significant delays after leaving Birmingham and we made plans to pick her up from Slidell instead of New Orleans to save a couple of hours.
By the time the train reached Laurel, MS, the estimated time of arrival at Slidell was after 11pm (original arrival time was about 7:15pm.) Just outside of Laurel, my daughter called to tell me that her train had hit a tree and they were stopped indefinitely for inspection. At this time, we decided to drive to Hattiesburg to pick her up. The train arrived at Hattiesburg around 11:10pm and finally arrived at Slidell around 2am.
While there were no issues with comfort, seating, etc. be aware of the potential for extreme delays.
