I don't see MSP and DTW both surviving as hubs after this is over. One is going to have to go unless they cut MSP-East Coast and reduce services to the South East in favor of DTW. Services DTW and W/SW would go too.
That's ridiculous. DL has been pretty transparent about where they have been making cuts so far. Which would normally indicates which stations they are willing to downsize.
They are not cutting their core hubs. You just have to see how many cities their core hubs still serve after the cuts. Most of them just got frequency cuts.
What did get cut are the new stations.
RDU got cut first - so I assume many of the routes out there never come back. I don't see it being down to just hub routes, but stuff like EWR/ORD/BWI/MIA/FLL/AUS are probably all goners.
CVG got cut next - I think this will get downsized not to the same degree as RDU, but their ff base there allows them to do serious downsizing without much damage to their pnl.
BOS got cut next - More likely to become a focus city after this. Question is whether this becomes a 110 to 130 flight station or 70 to 90 flight station. I expect some of the routes they cutin April/May to come back, but definitely not all of them. Not much point having a second Northeast TATL hub at this point when JFK slots will be widely available.
and then there are the other coastal hubs.
SEA/LAX - both of these still serve a lot of places and have well over 50 flights a day even with the significantly reduced schedule. They will probably come back as 150+ flights stations.
NYC - Even with all the cuts they made here, they have far and away the most number of flights of any airline. No way they don't pour more resource into New York when AA is clearly going to have to downsize NYC.
If DL is 1/3 smaller a year from now, it's not going to be core hubs or NYC that will see service to fewer places. Maybe a few, but mostly will just be down-gauges and frequency reductions.
