I apologize to the OP for stating they have no understanding of operations.
I'm not familar with everyone's background on here.

True through that there are many frequent flyers who really have no understanding of the operational complexities, challenges, and limitations of a large airline, particular in bad weather situations. It is unreasonable to expect an airline to run smoothly and ontime when in fat you can't even to the same on the highways. What happened over the past 3 days highlights that.

We haven't seen a storm like this that wiped out such a large area in awhile. I don't think we've seen a storm like this post-merger. Hopefully there will be some lessons learned out of this. A few things worked well, but many parts did not.

I think there could've been more proactive cancelations and a greater focus on resetting the operation once the storm cleared. NW learned this lesson the hard way in the past and used to do a good job of this in big storms.

I also think this storm amplified some of the challenges we used to see over the summer. Pre-merger (for both DL and NW) aircraft types, regional carriers, and tail routings were much more confined to a particular hub. Thus, if MSP went down, you didn't impact ATL or DTW and vice-versa.

It seems now you have multiple regionals across the hubs, and aircraft/crew routings within a day that span across multiple hubs. It is no wonder why so much was of position that let to delays and cancellations.

At the end of the day, it is easy for us on FT to complain and whine about it, but if you truly have a problem contact DL.
