Flights Lagos -> Washington (LOS-IAD) — USD Fares, Airlines, Frequency
4 scheduled departures a week link Lagos (LOS) in Nigeria with Washington (IAD) — one every 1.8 days on average — flown by 1 catalogued carrier at a scheduled block time near 11.5 hours.
Lagos to Washington connects Nigeria with the United States capital, with around 4 flights a week. The route carries the large Nigerian community in the Washington area visiting family, business travellers, students and connecting passengers. Block time is around eleven and a half hours.
Great-circle distance Lagos–Washington is about 8,752 km, computed from the stored coordinates of LOS (6.58, 3.32) and IAD (38.95, -77.46). What the figure fixes is the sector profile — 8,752 km against a scheduled 11.5-hour block time — and the fuel-and-crew economics behind the fare floor. It does not fix a compensation amount. The corridor touches the United States, where DOT rules cover refunds rather than delay compensation: a cancellation or a significant schedule change you decline is refunded automatically, while a long delay that still operates carries no statutory cash payout at all.
Airlines on this route
1 carrier is listed for LOS–IAD — UA — and we hold no carrier details for it, so this page states no baggage baseline, alliance or licensing country for it. Take those from the airline’s own conditions of carriage rather than from any table here.
United Airlines operates LOS-IAD, flying a full-service widebody with a checked baggage allowance and meals included. Washington Dulles is a United hub, so the route feeds a wide network of onward connections across the United States.
| Carrier | Baggage baseline | Alliance |
|---|---|---|
| UA (UA) | — | — |
We hold no carrier details for UA on LOS–IAD, so nothing on this page asserts its checked-baggage baseline, alliance membership or licensing country. No details on record is not the same as no allowance or no alliance — plenty of carriers we do not list are alliance members. For UA the airline’s own conditions of carriage are the source to use, and the operating carrier printed on your ticket is what decides which delay regulation you can claim under.
USD fares — LOS-IAD
$964 was the 2026-W29 reading in our weekly fare log for LOS–IAD, across 1 reading that range $964 to $964.
LOS-IAD fares move with the family calendar — the December holidays and the summer are the busiest and most expensive. For those dates, booking three to five months ahead is sensible. Outside the peaks, eight to twelve weeks usually secures a workable economy fare in USD.
Book 3-5 months ahead. Fares climb steeply around the December holidays and the summer, when diaspora travel peaks. That window is general guidance rather than a rule for this single pairing; on a corridor with 4 weekly departures, the practical constraint is often seat availability on the days you can actually travel, not the headline fare.
The fare family sits outside our data, and it is the piece that decides the real cost. A cached LOS–IAD quote records a price, a date and a carrier — not whether a 23 kg bag, a seat or a change is included. Where the corridor’s floor is set by a stripped fare, the ranking on screen reverses once the bag is added.
Passenger rights on LOS–IAD — and which ones do not apply
0 dollars of fixed delay compensation are due on LOS–IAD, the corridor’s United States endpoint notwithstanding. US DOT rules cover refunds, not compensation: a cancellation or a significant schedule change you decline triggers an automatic refund, but a long delay carries no statutory payout.
| Regime | When it applies | Remedy for a long delay / cancellation |
|---|---|---|
| US DOT | Flights to or from the United States. | No cash compensation for delays; an automatic refund is due for cancellations and significant schedule changes you decline (US DOT 2024 rule). |
| Montreal Convention 1999 | Any international itinerary — baggage and delay losses. | Compensation for lost, damaged or delayed baggage (up to 1,519 SDR per passenger) and for provable losses caused by delay (up to 6,303 SDR), limits in force since 28 December 2024. |
What does not apply matters as much as what does, because claim-management services will happily open a file either way. On LOS–IAD: EU261 does not reach this corridor at all — neither endpoint is an EU/EEA airport, and carrier nationality alone never triggers it and UK261 does not apply, since no leg touches a UK airport. Filing under a scheme that does not cover your itinerary costs weeks and gets a rejection, so match the regulation to the departure airport and the operating carrier before you start.
Do you need a visa to fly LOS–IAD?
Entry rule for United States, by passport: B1/B2 visitor visa unless your passport is from a Visa Waiver Program country. Fee $185 USD non-refundable application (MRV) fee for a B visitor visa; maximum stay Decided by the officer at the port of entry. That row names the passports it covers; for any other passport, check the linked government portal before booking.
| Entry type | Fee | Maximum stay | Official source |
|---|---|---|---|
| B1/B2 visitor visa unless your passport is from a Visa Waiver Program country | $185 USD non-refundable application (MRV) fee for a B visitor visa | Decided by the officer at the port of entry | United States official source |
Worth knowing before you book: Fee from the official US visa appointment service for South Africa. In-person interview at a US embassy or consulate.
The trap on LOS–IAD is not usually the destination visa — it is the transit. A connection can put you airside in a third country that requires a transit visa for your nationality even though you never leave the terminal, and airlines deny boarding at origin when documentation for the whole itinerary is not in order. Check every country your ticket touches, not just United States, and check it against your own passport rather than a fellow traveller’s.
Search live fares
4 weekly departures across 1 carrier mean a live LOS–IAD search returns several price points for the same day; our weekly fare log has recorded readings as low as $964 (see the dated history on this page). Scheduled nonstop block time is 11.5 hours, so any result far above that is connecting whatever the screen says.
Search LOS -> IAD on Aviasales ->
Three checks make a live LOS–IAD result comparable. Fix the passenger count and cabin first, because a per-passenger fare and a party total look identical on a results page. Then read the elapsed time next to the price — a one-stop itinerary and the 11.5-hour nonstop are different products at the same number. Then check whether the fare carries the bag you are actually taking.
Flexible dates are the highest-leverage setting on this corridor. Our own cache shows month-to-month movement on LOS–IAD that dwarfs the difference between booking gates, so one search across a whole month tells you more than five searches on a single date. Where the dates cannot move — a pilgrimage window, a school term, a contract start — book earlier instead of searching harder.
About Washington
6 catalogued corridors in this site’s data reach Washington (IAD), Dulles International, ICAO KIAD, from 6 catalogued origins and 3 carriers in total. That count is this site’s coverage of Washington, not the airport’s published schedule. Each of those corridors has its own guide with carriers, weekly frequency, scheduled block time and whatever the fare cache holds.
Washington is the capital of the United States, home to a substantial Nigerian community in its wider metropolitan area. For travellers from Lagos it is most often a family-visit destination, as well as a business and institutional one.
Beyond LOS, our catalogue reaches Washington from 5 other origins: Abuja (ABV), Accra (ACC), Addis Ababa (ADD), Johannesburg (JNB) and Nairobi (NBO). That matters when the LOS–IAD fare is unattractive: on a continent where positioning flights are cheap, flying out of a different gateway is a real option, and each of those corridors has its own guide, carriers and cached fare floor on this site.
On the ground United States uses USD, while every fare on this site is quoted in USD. That split is deliberate: USD is the only currency that makes a Lagos fare and a Nairobi fare comparable on one page, but it means the card you pay with will convert twice if your bank settles in a third currency. Airline sites often offer payment in USD or in your home currency — the airline’s own rate is rarely the better of the two.
