What ORD to DUB looks like
The ORD to DUB sector, the carriers on it and the flying time, before anything is promised to anybody.
Chicago ORD to Dublin DUB is a long haul sector of 5,895 km by great circle, flown nonstop 4.6 times a day.
At the cruise speed this site models for 5,895 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 7h 36m.
Chicago ORD is a major hub in the network held here, 295 scheduled destinations and 1,461 departures a day. Dublin DUB has 198 destinations and 462.1 departures a day.
Chicago carries about 3.2 times the departures of Dublin, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Dublin is 6 hours ahead of Chicago all year.
The pair sits between the Americas and Europe, a corridor where the site already publishes 36 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on ORD to DUB from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| ORD to DUB | 4.57 | 32 | Aer Lingus, Air France, American Airlines, United Airlines |
| DUB to ORD | 4.14 | 29 | Aer Lingus, American Airlines, United Airlines |
4 carriers are recorded on the sector, so a missed departure is normally a rebooking rather than a lost day.
At 4.6 times a day there is usually another departure within a few hours, which is what makes a same day booking on this pair realistic.
Between them the two directions put about 61 departures a week on ORD to DUB, which is the number that decides whether a seat can be found today or on Thursday.
The clock from collection to signature
The same ground timings the route calculator starts from, applied to the 7h 36m block time on ORD to DUB. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to ORD | 90 min | 1h 30m |
| At ORD before departure | 180 min | 4h 30m |
| ORD to DUB in the air, estimated | 456 min | 12h 06m |
| Formalities at DUB | 90 min | 13h 36m |
| Delivery run in Dublin | 45 min | 14h 21m |
| Door to door | 861 min | 14h 21m |
On the desk standard ground timings, ninety minutes to collect and reach the airport, three hours at the airport before departure, ninety minutes of arrival formalities and a forty five minute delivery run, the door to door figure for ORD to DUB is 14h 21m.
A courier who leaves Chicago at 09:00 local is on the ground in Dublin at about 22:36 local and at the door by 00:51 the following day.
Working backwards from a six in the evening handover in Dublin, nothing leaving Chicago inside a normal working day arrives in time, so this pair is an overnight and a next morning delivery rather than a same day one.
At 14h 21m the mission uses most of a sixteen hour duty day, which leaves no room for a delay before a rest at the far end becomes the honest answer.
When the nonstop does not work
Every airport that joins the two ends, ranked by when they land, among the ones whose weaker leg is dependable enough to plan on. Connection time is allowed for the size of the hub. 53 of them join ORD to DUB.
| Connecting at | ORD to hub, flights a day | Hub to DUB, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Montreal YUL | 10.71 | 0.71 | 5,971 | 9h 32m |
| Detroit DTW | 21.43 | 1 | 5,974 | 9h 33m |
| Reykjavik KEF | 3.43 | 1.14 | 6,223 | 9h 36m |
| Toronto YYZ | 18.86 | 5.14 | 5,961 | 9h 37m |
| Cleveland CLE | 17.29 | 1 | 6,069 | 9h 42m |
| Boston BOS | 30.14 | 4.57 | 6,194 | 9h 49m |
With 4.6 times a day on the nonstop, a connection here is a disruption plan rather than a routing, and it is listed because a closed runway or a cancellation wave is exactly when nobody has time to work it out.
53 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Montreal YUL, where the weaker of the two legs still runs 5 times a week.
Through YUL the routing covers 5,971 km against the 5,895 km nonstop track and takes about 9h 32m in the air and on the ground at the hub, allowing 75 minutes to connect at an airport of that size.
That is only 1h 56m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Detroit DTW at 9h 33m and Reykjavik KEF at 9h 36m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Chicago, Chicago MDW is 25 km away by great circle and carries 208 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
If nothing suitable leaves Dublin, Belfast BFS is 137 km away by great circle and carries 47 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.

Where this came from, and where to look next
- Carriers and frequencies: AeroDataBox scheduled route statistics, retrieved 2026-09-07. Average daily flights, not a timetable.
- Distances: great circle from published coordinates. They read short against a flown track, which is why the block time above applies a factor to them.
- Block and connection times: the same model the route calculator lower down this page runs, at the same rounding.
- Restrictions: the airport notes file, checked 2026-09-07.
- Industrial sites: public company information. Nothing here says or implies that any company named is a customer of any courier operator.
Who publishes this. OnBoard Courier is a placement desk in Dubai. An assignment is carried out by a vetted partner operator, with the desk as the single point of contact from the quote to the signature. This page exists because our own dispatchers need the answer for ORD to DUB in the twenty minutes before a promise is made, and a reference only one operator can read is not a reference. Free to read, quote and cite. Found an error? Tell us and we will correct it.
If you need something moved rather than looked up, the desk prices a hand carry in fifteen minutes.
