What YUL to IAH looks like
The YUL to IAH sector, the carriers on it and the flying time, before anything is promised to anybody.
Montreal YUL to Houston IAH is a medium haul sector of 2,549 km by great circle, flown nonstop about once a day.
At the cruise speed this site models for 2,549 km, 830 km an hour, and thirty minutes of taxi at the two ends, the flight blocks at about 3h 45m.
Montreal YUL is a major hub in the network held here, 157 scheduled destinations and 317.8 departures a day. Houston IAH has 197 destinations and 641 departures a day.
Houston is one hour behind of Montreal all year.
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 YUL to IAH from the scheduled route statistics, both directions, with the operating carriers named.
| Direction | Flights a day | Flights a week | Operated by |
|---|---|---|---|
| YUL to IAH | 1.29 | 9 | Air Canada |
| IAH to YUL | 1.14 | 8 | Air Canada |
One carrier holds the sector, Air Canada, so a cancellation has no second nonstop behind it and the connections below stop being theoretical.
Between them the two directions put about 17 departures a week on YUL 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 3h 45m block time on YUL 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 YUL | 90 min | 1h 30m |
| At YUL before departure | 180 min | 4h 30m |
| YUL to IAH in the air, estimated | 225 min | 8h 15m |
| Formalities at IAH | 90 min | 9h 45m |
| Delivery run in Houston | 45 min | 10h 30m |
| Door to door | 630 min | 10h 30m |
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 YUL to IAH is 10h 30m.
A courier who leaves Montreal at 09:00 local is on the ground in Houston at about 11:45 local and at the door by 14:00 the same day.
Working backwards from a six in the evening handover in Houston, the last useful departure from Montreal is around 13:00 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 YUL to IAH.
| Connecting at | YUL to hub, flights a day | Hub to IAH, flights a day | Track, km | Estimated, gate to gate |
|---|---|---|---|---|
| Columbus CMH | 1.14 | 2.86 | 2,549 | 5h 31m |
| Detroit DTW | 4.29 | 7.57 | 2,582 | 5h 33m |
| St Louis STL | 1 | 3.86 | 2,634 | 5h 36m |
| Toronto YYZ | 30.86 | 4.57 | 2,567 | 5h 38m |
| Cleveland CLE | 1.14 | 2.29 | 2,551 | 5h 40m |
| Pittsburgh PIT | 1.14 | 3.14 | 2,563 | 5h 41m |
One nonstop a day means one chance a day, so the connections below are what a consignment that arrives at YUL in the afternoon actually flies on.
55 airports connect the two ends on the scheduled network held here. The quickest of the dependable ones is Columbus CMH, where the weaker of the two legs still runs about once a day.
Through CMH the routing covers 2,549 km against the 2,549 km nonstop track and takes about 5h 31m 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 46m 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 5h 33m and St Louis STL at 5h 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 Montreal, Ottawa YOW is 151 km away by great circle and carries 45 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.

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 YUL 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.
