Unknown. It appeared on a list of requested CARES act exemption drops from AS about three weeks ago and has been operating as a tag-on to SEA-MSP during the pandemic. However, since that time the OAG threads here have indicated that rather than disappearing it is returning to a daily direct flight (rather than tag-on, which would seem good news?) in July and there has been no further news on a drop. Your guess is as good as mine, maybe someone on this thread has more info?
I have flown the CMH-SEA through MSP 4 times this month. I hate the tag on, but better to have this service than none. Hopefully it sticks.
It did so well last summer (load factors above 95%) that pre-pandemic it was slated to go from 1x 319/320 to 2x 738 this year. DL added a competing a220 segment too. If air traffic returns to anything quasi-normal I see no reason it would be discontinued.
I don't know how much to read into it, but the fact it's a non-stop again as opposed to continuing with the MSP tag seems encouraging, especially since they're still running tags (as is the case with SEA-PIT-CHS, though I get that SEA-CHS is dependent on Boeing traffic).
