When I lived in Detroit, I was forced to fly Delta. 75% of flights at Detroit Metro Airport were Delta.
Thanks to the recession, I had to move to Maryland for a job. The family didn’t move till we sold the house so for 8 months, I came home every second or third weekend. I drove every time. (9-10 hours each way)
The weekend we were scheduled to move, I decided to fly. Delta. Stupid.
The delayed the flight several times along with a second flight to Detroit. Finally told us to go home and try again later.
There was no weather or other outside influence.
I knew someone who was driving to Detroit the next morning and rode with them.
I fly somewhat frequently for work and do my best to never fly Delta. I think maybe twice in the last nine years.
Surprised your flight from Maryland to Detroit didn’t have a stopover in Atlanta
