What CUN to IAH looks like
The CUN to IAH sector, the carriers on it and the flying time, before anything is promised to anybody.
Cancun CUN to Houston IAH is a medium haul sector of 1,307 km by great circle, flown nonstop 5.6 times a day.
At the cruise speed this site models for 1,307 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 2h 10m.
Cancun CUN is a large airport in the network held here, 85 scheduled destinations and 183.5 departures a day. Houston IAH has 197 destinations and 641 departures a day.
Houston carries about 3.5 times the departures of Cancun, so a courier who has to be rebooked has far more to work with at one end of this pair than at the other.
Houston runs one hour behind of Cancun in January and no time shift at all 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 CUN to IAH from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| CUN to IAH | 5.57 | 39 | United Airlines |
| IAH to CUN | 5.71 | 40 | 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.
At 5.6 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 79 departures a week on CUN to IAH, 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 2h 10m block time on CUN to IAH. Change any of them in the tool further down and the total moves with them.
| Stage | Allowed | Elapsed |
|---|---|---|
| Collection and the run to CUN | 90 min | 1h 30m |
| At CUN before departure | 180 min | 4h 30m |
| CUN to IAH in the air, estimated | 130 min | 6h 40m |
| Formalities at IAH | 90 min | 8h 10m |
| Delivery run in Houston | 45 min | 8h 55m |
| Door to door | 535 min | 8h 55m |
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 CUN to IAH is 8h 55m.
A courier who leaves Cancun at 09:00 local is on the ground in Houston at about 10:10 local and at the door by 12:25 the same day.
Working backwards from a six in the evening handover in Houston, the last useful departure from Cancun is around 14:35 local.
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. 55 of them join CUN to IAH.
| Connecting at | CUN to hub, flights a day | Hub to IAH, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Monterrey MTY | 14.71 | 8.14 | 2,110 | 4h 49m |
| Tampa TPA | 1 | 3.71 | 2,153 | 5h 00m |
| Puebla PBC | 3 | 1.57 | 2,460 | 5h 08m |
| Dallas DFW | 6.01 | 19.57 | 2,019 | 5h 09m |
| San Luis Potosi SLP | 1.41 | 2.57 | 2,482 | 5h 10m |
| Queretaro QRO | 2.86 | 4.29 | 2,533 | 5h 14m |
With 5.6 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.
55 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Monterrey MTY, where the weaker of the two legs still runs 8.1 times a day.
Through MTY the routing covers 2,110 km against the 1,307 km nonstop track and takes about 4h 49m in the air and on the ground at the hub, allowing 60 minutes to connect at an airport of that size.
That is 2h 39m more than the nonstop, which is the price of a missed departure on this pair.
Behind it, Tampa TPA at 5h 00m and Puebla PBC at 5h 08m 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.

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 CUN to IAH 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.
