Seems like interest in TRANSATLANTIC service from CMH is waning!
Can you tell us why you think that?
As for the counterargument, the March 2018 CRAA Board Minutes said:
"2018 Air service strategic targets:
(starts in March with a new carrier, no less)
(Hell must have frozen over because CMH-SFO is finally a thing starting in June)
-European hub service"https://columbusairports.com/storage/pr ... al-002.pdf
Not only the two checkmarks above, but there's the return of SLC, which was also named as on the wish list at some point along the way. By that metric, you can draw two things:
-The airport, with the help of the City and local industry, is in the mood to spend to add service, and
-Two of the three from that list are in the rear-view mirror, leaving one big target in the windshield.
I think it's probably too late for 2019, as TATL announcements tend to happen in the Fall for service in the Summer, but I wouldn't say they've given up on it by any stretch of the imagination. Not only has the airport talked about it and explicitly named the likely operator (DL, who has a track record of adding P2P TATL and has the airplane (757) to do it), but there seemed to be some chatter about it amongst their employees at the airport.
Will CMH ever get it? That's out of our hands, but the gains the airport has made this year are much more than we've seen in previous years, so I'd say it's definitely still possible.
