United Airlines in the network the desk measures
Computed on 2026-09-07 from AeroDataBox scheduled route statistics. The desk holds departure schedules for 571 airports, and for the UA code that yields 1,088 city pairs across 390 of them. It is a measured sample of the published timetable and not the whole of it. Frequencies move with the season, and a quote is priced on the flights running the day you ask.

The schedule the desk holds carries the UA code on 1,088 city pairs, reaching 390 airports in 70 countries and territories. Some of those sectors are flown by United Airlines and some are sold under its code and flown by a partner, which is how the published timetable states it and how a booking has to be read. 80.5 per cent of those airports sit on time zones in the Americas, and the next largest block is on European time zones.
01The longest sector held for the carrier is San Francisco (SFO) to Singapore (SIN) at about 13,582 km, and the shortest is Cleveland (BKL) to Cleveland (CLE) at about 18 km. 141 of the 1,088 pairs run past 5,000 km, so the carrier carries a courier across a continent on some sectors and shuttles on the rest. The airport that appears most often on those pairs is Chicago (ORD), on 196 of them, which is 18 per cent of everything held under this code.
02The thickest sector under the code is New York (LGA) to Chicago (ORD) at about 36.1 movements a day, which across a full day is roughly one every 0.7 hours. On a sector at that cadence a missed departure costs a wait rather than a night. 446 of the 1,088 pairs run four or more times a day and 182 run once a day or less. The second figure is the one that matters when a consignment leaves the factory late, because on those sectors the desk will quote a different carrier rather than promise an hour it cannot hold. After Chicago (ORD) the code leans on Denver (DEN) on 194, Houston (IAH) on 162, Newark (EWR) on 155 pairs respectively, and those are the airports a dispatcher looks at second when the first routing is full.
The sectors that carry the UA code most often
The 16 sectors the UA code appears on most often, out of 1,088. Flights a day is the average daily scheduled movement on the busier of the two directions, as held on 2026-09-07. The schedule lists a code against a sector whether the carrier operates it or sells it, so read this as where the code can be booked. Distances are great circle, computed from the published coordinates of the two airports.
How a courier reaches Chicago from the Gulf
The schedule the desk holds shows no UA service into a UAE airport, so a courier does not board this carrier in Dubai. The routing is built the other way round: a Gulf carrier takes the first leg to Chicago (ORD), and United Airlines carries the second.
The first leg, measured. These are the 2 links the desk holds from a UAE gateway into Chicago (ORD), the airport this code is booked through most often.
Night restrictions on the airports the UA code uses
A hand carry is bought for the hours it saves, and an airport that will not take a movement after a certain hour can spend those hours back. 19 of the 390 airports this code is booked through carry a restriction the desk holds in writing, checked 2026-09-07. Exemptions and seasonal variations exist, and the desk confirms the position with the airport or the carrier before it books.
- Tokyo (NRT), night restrictions. Scheduled movements are limited between 23:00 and 06:00 local; late departures usually route through Haneda instead.
- London (LHR), night restrictions. A night quota system limits movements between 23:30 and 06:00 local. Very few scheduled departures in that window.
- Frankfurt-am-Main (FRA), night restrictions. No scheduled take offs or landings between 23:00 and 05:00 local. A late evening departure that slips past 23:00 does not go until morning.
- Tokyo (HND), night operations. Operates around the clock; the preferred Tokyo gate for a late departure.
- Munich (MUC), night restrictions. Scheduled movements are limited between 22:00 and 06:00 local, with a core quiet period from midnight to 05:00.
- Amsterdam (AMS), night restrictions. Night operations between 23:00 and 07:00 local are limited by an annual cap and runway rules.
Published lanes that carry the UA code
The site publishes a page for 346 courier lanes. United Airlines appears in the schedule on 10 of them, and the one it flies most is Houston to Monterrey at about 8.1 movements a day. That overlap is the honest test of whether a carrier is useful to this desk rather than merely famous.
- Houston to Monterrey, about 8.1 scheduled flights a day on the busier direction, 662 km.
- San Francisco to Taipei, about 8.1 scheduled flights a day on the busier direction, 10,391 km.
- Seoul to San Francisco, about 7.7 scheduled flights a day on the busier direction, 9,085 km.
- Shanghai to Los Angeles, about 6.4 scheduled flights a day on the busier direction, 10,415 km.
- Chicago to Frankfurt, about 5.7 scheduled flights a day on the busier direction, 6,970 km.
