What NRT to IAH looks like
The NRT to IAH sector, the carriers on it and the flying time, before anything is promised to anybody.
Tokyo NRT to Houston IAH is an ultra long sector of 10,669 km by great circle, flown nonstop about twice a day.
At the cruise speed this site models for 10,669 km, 880 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 13h 21m.
Tokyo NRT is a large airport in the network held here, 117 scheduled destinations and 361.5 departures a day. Houston IAH has 197 destinations and 641 departures a day.
Houston runs 15 hours behind of Tokyo in January and 14 hours behind in July, because the two ends do not change their clocks together.
The pair sits between the Americas and Asia Pacific, a corridor where the site already publishes 16 written lanes that go into customs and ground detail this page does not.
Who flies the sector, and how often
Average daily frequencies on NRT to IAH from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| NRT to IAH | 2.86 | 20 | United Airlines, ZIPAIR Tokyo |
| IAH to NRT | 1.57 | 11 | United Airlines, ZIPAIR Tokyo |
Two carriers hold the sector, United Airlines and ZIPAIR Tokyo, which gives a missed departure somewhere to go without leaving the nonstop.
The two directions are not level: NRT to IAH runs about twice a day, the return runs about once a day, and a round trip has to be planned around the thinner of the two.
Between them the two directions put about 31 departures a week on NRT 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 13h 21m block time on NRT 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 NRT | 90 min | 1h 30m |
| At NRT before departure | 180 min | 4h 30m |
| NRT to IAH in the air, estimated | 801 min | 17h 51m |
| Formalities at IAH | 90 min | 19h 21m |
| Delivery run in Houston | 45 min | 20h 06m |
| Door to door | 1,206 min | 20h 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 NRT to IAH is 20h 06m.
A courier who leaves Tokyo at 09:00 local is on the ground in Houston at about 07:21 local and at the door by 09:36 the same day.
Working backwards from a six in the evening handover in Houston, the last useful departure from Tokyo is around 17:24 local.
At 20h 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. 24 of them join NRT to IAH.
| Connecting at | NRT to hub, flights a day | Hub to IAH, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Anchorage ANC | 1.71 | 1.14 | 10,763 | 14h 58m |
| Vancouver YVR | 3.29 | 3.43 | 10,672 | 15h 06m |
| Seattle SEA | 2.14 | 6.86 | 10,669 | 15h 06m |
| Calgary YYC | 1.14 | 3.57 | 10,759 | 15h 25m |
| Dallas DFW | 1.14 | 19.57 | 10,684 | 15h 28m |
| Denver DEN | 1.14 | 15.57 | 10,681 | 15h 28m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at NRT in the afternoon actually flies on.
24 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Anchorage ANC, where the weaker of the two legs still runs about once a day.
Through ANC the routing covers 10,763 km against the 10,669 km nonstop track and takes about 14h 58m 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 37m more than the nonstop, which is close enough that a connection is worth taking when the nonstop is full or badly timed.
Behind it, Vancouver YVR at 15h 06m and Seattle SEA at 15h 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 Tokyo, Tokyo HND is 60 km away by great circle and carries 105 scheduled destinations of its own, which is usually a shorter road transfer than a lost day.
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.
Restricted hours at either end
Widely documented operating restrictions, checked 2026-09-07. Exemptions and seasonal variations exist, so confirm with the carrier before relying on any of them.
Tokyo NRT is shut to scheduled movements between 23:00 and 06:00 local, so a collection in Tokyo that runs late does not simply catch a later flight, it waits for the morning and loses a working day in Houston.
Tokyo NRT, night restrictions: Scheduled movements are limited between 23:00 and 06:00 local; late departures usually route through Haneda instead.

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 NRT 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.
