The distance between the airports is about 3,520 miles.", "methodology": "Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.", "toolsUsed": ["flight_schedule"]}, "q3": {"question": "What are the ground transportation options in Washington?", "answer": "From Washington Dulles International Airport (IAD), the Silver Line Express bus connects to the Wiehle-Reston East Metrorail station for $5, after which the Metrorail Silver Line provides direct access to downtown Washington, D.C. Taxis operated by Washington Flyer are available 24/7 from the baggage claim area, while ride-share services like Uber and Lyft offer authorized pickup. Shared van services such as SuperShuttle and Supreme Shuttle also operate from the airport. The Metrorail is a popular and cost-effective option for reaching the city center, though it does not run overnight; taxis and ride-shares are the fastest door-to-door choices.", "toolsUsed": [], "references": [{"url": "https://flydulles.com/flight-schedule-dulles-international-airport-iad", "title": "flydulles.com - Flight Schedule - Dulles International Airport (IAD)", "time_published": "2022-03-01T00:00:00Z"}, {"url": "https://parking.flydulles.com/economy-parking", "title": "Dulles International Airport Parking | Economy Parking", "time_published": "2026-02-06T00:00:00Z"}, {"url": "https://www.mwaa.com/ipw-2017-archived", "title": "IPW 2017 - Archived", "time_published": "2021-02-01T00:00:00Z"}, {"url": "https://www.mwaa.com/policefireems/fire-ems/fire-ems-washington-dulles-international-airport", "title": "mwaa.com - Fire & EMS at Washington Dulles International Airport", "favicon": "https://www.mwaa.com/themes/custom/mwaa_barrio/favicon.ico", "time_published": "2023-09-01T00:00:00Z"}, {"url": "https://en.wikipedia.org/wiki/Dulles%20International%20Airport", "title": "Dulles International Airport", "time_published": "2026-04-30T14:07:38Z"}]}, "q4": {"question": "When is the cheapest time to fly from Lima to Washington?", "answer": "The cheapest months to fly from Lima to Washington are April, September, and October, with average fares around $508–$541, while December and July are the most expensive, averaging $720 and $662 respectively.", "methodology": "This 'good deal' estimate shows a representative best price for each departure date across roughly a 12-month window (about 3 months back and 9 months forward). It is built from real flight prices found by Priceline users searching this route, accumulated into a price history for each departure date. Rather than weighting all of that history equally, we apply exponential time decay so recent prices dominate — a price seen yesterday counts almost in full, one from about a month ago roughly a third, and prices from a few months back very little — giving a figure that tracks today's market instead of a stale long-run average. Clear price outliers are removed before any calculation, departure dates with no observations are filled in from nearby dates, and the resulting curve is lightly smoothed so it reads as a clean seasonal trend rather than day-to-day noise. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.", "toolsUsed": ["seasonal_prices"]}, "q5": {"question": "How far in advance should I book tickets from Lima to Washington?", "answer": "For flights from Lima to Washington, the optimal booking window is 6 to 9 weeks before departure, with an average fare of $620. Booking around 55 days out yields the best single-day price at $617, while last-minute tickets average $706.", "methodology": "This booking-window guidance is built from the same real flight prices found by Priceline users searching this route, re-grouped by how many days before departure each price was seen (from the departure day out to about 180 days ahead) across the route's price history. At each booking lead time we report the 25th-percentile price — the cheaper end of what travelers were quoted, rather than the rock-bottom minimum (which can be a fluke) or the average (which is pulled up by expensive last-minute fares). The buy-or-wait advice then applies a risk premium that grows as departure approaches, since seat availability shrinks and prices become less predictable; using that adjusted curve we flag windows where waiting is likely to save a meaningful amount (at least $20 or 5%) versus windows where booking now is the better call. Isolated single-day recommendations are filtered out, so the advice only reflects a window that holds for several days in a row. For this route, fares for the requested travel direction were unavailable, so the pattern shown is derived from the reverse direction, which shares the same seasonal demand cycle.", "toolsUsed": ["booking_timing"]}, "q6": {"question": "Are overnight (red‑eye) flights available from Lima to Washington?", "answer": "No nonstop red‑eyes operate from Lima to Washington, but several one‑stop itineraries have an overnight long leg.

United also operates a handful of daily connections via Newark.", "methodology": "Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports.

Miami and Fort Lauderdale offer the shortest routing from Lima with frequent onward connections to Washington. Houston and Atlanta provide broad domestic networks and efficient transfer processes, often with single-terminal connections. All are within the U.S., so no additional transit visas are required beyond your U.S. entry documents."}, "q10": {"question": "Which months have the best weather for traveling to Washington?", "answer": "April to May and September to October offer mild temperatures, blooming or colorful foliage, and fewer tourists than summer."}, "q11": {"question": "What documents should I bring with me to the airport when flying from Lima to Washington?", "answer": "Bring a passport valid for at least six months, a valid U.S. visa or ESTA authorization, proof of onward or return travel, a payment method for baggage and any required vaccination certificates."}, "q12": {"question": "Which airport should I use in Washington?", "answer": "Washington Dulles is the primary international gateway, 42 km west of downtown, with United and Star Alliance hubs.

Baltimore/Washington International is 48 km northeast, with Southwest and low‑cost carriers."}, "q13": {"question": "How do I get to Jorge Chávez Intl Airport from the city center?", "answer": "From central Lima, taxis and ride‑share services like Uber or Cabify are the most popular and quickest way to reach Jorge Chávez International Airport, which is about 11 km northwest of the historic center. Official airport taxis are available from designated ranks, while ride‑share apps offer a convenient and often cheaper alternative. Public buses and minibuses (micros) also serve the airport but are slower and less comfortable, especially with luggage.
