What IAH to EZE looks like
The IAH to EZE sector, the carriers on it and the flying time, before anything is promised to anybody.
Houston IAH to Buenos Aires EZE is an ultra long sector of 8,173 km by great circle, flown nonstop about once a day.
At the cruise speed this site models for 8,173 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 10h 21m.
Houston IAH is a major hub in the network held here, 197 scheduled destinations and 641 departures a day. Buenos Aires EZE has 58 destinations and 109.4 departures a day.
Houston carries about 5.9 times the departures of Buenos Aires, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Buenos Aires runs 3 hours ahead of Houston in January and 2 hours ahead in July, because the two ends do not change their clocks together.
The pair sits inside the Americas, a corridor where the site already publishes 13 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on IAH to EZE from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| IAH to EZE | 1.43 | 10 | United Airlines |
| EZE to IAH | 1.14 | 8 | United Airlines |
One carrier holds the sector, United Airlines, so a cancellation has no second nonstop behind it and the connections below stop being theoretical.
Between them the two directions put about 18 departures a week on IAH to EZE, 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 10h 21m block time on IAH to EZE. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to IAH | 90 min | 1h 30m |
| At IAH before departure | 180 min | 4h 30m |
| IAH to EZE in the air, estimated | 621 min | 14h 51m |
| Formalities at EZE | 90 min | 16h 21m |
| Delivery run in Buenos Aires | 45 min | 17h 06m |
| Door to door | 1,026 min | 17h 06m |
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 IAH to EZE is 17h 06m.
A courier who leaves Houston at 09:00 local is on the ground in Buenos Aires at about 22:21 local and at the door by 00:36 the following day.
Working backwards from a six in the evening handover in Buenos Aires, nothing leaving Houston 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 17h 06m the mission is past the sixteen hour duty day a single courier is planned against, so it is quoted with a rest at the far end or with a second courier, and never as a turnaround.
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. 21 of them join IAH to EZE.
| Connecting at | IAH to hub, flights a day | Hub to EZE, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Quito UIO | 2 | 0.71 | 8,174 | 11h 51m |
| Medellin MDE | 1.14 | 1.14 | 8,260 | 11h 57m |
| Panama City PTY | 2.43 | 7.29 | 8,207 | 12h 06m |
| Bogota BOG | 2.43 | 3.43 | 8,274 | 12h 13m |
| Mexico City MEX | 10.29 | 1.14 | 8,629 | 12h 44m |
| Miami MIA | 9.29 | 6 | 8,668 | 13h 04m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at IAH in the afternoon actually flies on.
21 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Quito UIO, where the weaker of the two legs still runs 5 times a week.
Through UIO the routing covers 8,174 km against the 8,173 km nonstop track and takes about 11h 51m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is only 1h 30m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Medellin MDE at 11h 57m and Panama City PTY at 12h 06m hold the same connection, so a booking has three hubs to try before it has to wait for the nonstop.
If nothing suitable leaves Houston, Houston HOU is 38 km away by great circle and carries 145 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
If nothing suitable leaves Buenos Aires, Buenos Aires AEP is 31 km away by great circle and carries 57 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 IAH to EZE 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.
