CMH Columbus

How deep the CMH board really is

The table above says where a courier can fly from CMH. This reads the same 118 destinations back for the questions a dispatcher asks second: how much of the board rests on one airline, how much of it runs less than daily, whether the return leg is as thick as the outbound and what the clock here does to a Gulf working day, all of it computed on 2026-09-07 from AeroDataBox scheduled route statistics.

• 74of the 118 destinations are flown by one airline
• 81destinations run less than once a day
• 16destinations have four or more departures a day
• 35.6%of the destinations name NetJets Aviation, the largest presence here

Who holds the departures at CMH

44 airlines appear on the CMH board and they do not hold it evenly. NetJets Aviation is on 42 of the 118 destinations, 35.6 per cent of them, and on 22 of those it is the only airline flying the sector. The destinations it appears on carry 41.8 of the 167.8 departures a day this airport files, though other airlines fly some of the same sectors, so read that as reach rather than as a share of the aircraft.

The next largest presence is Southwest Airlines on 21 destinations. 20 of the 44 airlines at CMH appear on a single destination each, which is the long tail every airport carries, and none of it is a rebooking option when the sector you need is the one that fell over.

That is a middling concentration at CMH: one airline on 35.6 per cent of the destinations and the other 64.4 per cent spread across 43 airlines. A cancellation inside the NetJets Aviation network is often survivable inside the same booking, but on the 76 destinations NetJets Aviation does not touch, a rebooking means moving to a carrier the desk has to check for a through fare first.

How much of the CMH board is daily

Of the 118 destinations, 37 are flown at least once a day and 81 are not, 46 of them running once a week or less. The median destination on the CMH board is flown 2 times a week.

An average of 0.14 flights a day is the schedule statistic, and it is worth translating it before anything is promised to anybody: CMH to Youngstown/Warren (YNG) is about one a week, so a missed departure there is not a delay of hours, it is the next slot.

The five busiest destinations carry 48.1 of the 167.8 departures a day, 28.7 per cent of the whole board. With 68.6 per cent of the 118 destinations running less than daily, this is a board that rewards booking the outbound before the collection is confirmed rather than after.

The ten destinations out of CMH where one airline holds the sector and files fewer than seven departures a week, with the weekly figure taken as the average daily rate multiplied by seven rather than as a fixed timetable. 54 further destinations sit in the same position and are listed in the board above.

The way back from CMH

The desk holds the return direction for 41 of the 118 destinations, and a courier plans the way back on those figures rather than on the outbound. On two of them the return into CMH runs thinner than the outbound by more than a quarter. The widest gaps are Pittsburgh (PIT) at 0.86 out a day against 0.29 back and Greenville (GSP) at 0.43 out a day against 0.29 back.

It runs the other way as well: Washington (IAD) files 7.3 a day back into CMH against 5 outbound, which is the shape that strands a courier at this end rather than at the far end.

The clock at CMH

CMH keeps America/New_York time, eight hours behind Dubai in summer and nine hours behind in winter, because the clock here moves and the Gulf clock does not.

When it is 09:00 on a Dubai working morning it is 01:00 at CMH, so a nine to six day at each end overlaps for an hour. That is a narrow window for a signature, a customs query or an authority to release, and it is the reason a consignment for CMH is briefed the day before rather than on the morning it flies.

Where CMH turns up on the rest of this site

The airport also sits behind the United States country desk, which sets out the customs practice, the working week and the road legs behind this airport.

The site publishes 9 airport pair pages that start or end at CMH, each with the distance, the block time, the carriers on the sector and a door to door clock. The busiest are Columbus to Detroit (DTW), Columbus to Washington (DCA) and Columbus to Philadelphia (PHL).

Twelve courier postings name CMH as the airport a courier here flies from: Columbus, Cincinnati and Dayton.

To price a movement rather than read the board, the route calculator opens with CMH already set as the origin, and it works out the flying time, the distance and the delivery hour for any of the 118 destinations above.
