Frequently Asked Questions
How does the flight duration calculator work?
Our flight duration calculator works by accounting for timezone differences between departure and arrival airports. You enter your departure airport, departure date and local time, then your arrival airport, arrival date and local time. The calculator then computes the actual flight duration by converting both times to UTC and calculating the difference. This is particularly useful for international flights crossing multiple time zones where the local arrival time might appear earlier or later than expected.
How do you calculate flight distance between two airports?
We use the Haversine formula to calculate the great-circle distance between any two airports based on their geographic coordinates. This gives you the shortest distance over the Earth's surface in kilometers, miles, and nautical miles. Each distance page also shows an estimated flight time based on an average cruise speed of 850 km/h plus 30 minutes of overhead for takeoff and landing. You can check the distance between any pair of airports using our Airport Distance Calculator on the homepage or by visiting the direct distance page (e.g., /distance/jfk-lhr).
What information is shown on an airport distance page?
Each distance page provides a detailed comparison between two airports, including: exact distance in kilometers, miles, and nautical miles; estimated flight time; timezone difference with a real-time clock comparison; flight heading and compass direction; route classification (regional, short-haul, medium-haul, long-haul, or ultra-long-haul); elevation difference; a side-by-side airport comparison table with IATA/ICAO codes, cities, countries, timezones, and coordinates; contextual information about the route; and links to related routes for further exploration.
How many airports are in your database?
Our comprehensive database contains nearly 30,000 airports and airfields worldwide. This includes all major international airports, regional airports, domestic airports, military airfields, heliports, and smaller private airfields. Each airport entry includes its name, city, country, state/region, IATA code (if assigned), ICAO code, timezone, elevation, and precise coordinates. You can browse airports by country, continent, city, or timezone, and each airport has a dedicated detail page.
What is an IATA airport code?
IATA (International Air Transport Association) codes are three-letter identifiers assigned to airports worldwide. These codes are used on boarding passes, baggage tags, and flight booking systems. Examples include JFK for John F. Kennedy International Airport in New York, LHR for London Heathrow, LAX for Los Angeles International, CDG for Paris Charles de Gaulle, and DXB for Dubai International. Not all airports have IATA codes - typically only airports with commercial passenger service receive them.
What is an ICAO airport code?
ICAO (International Civil Aviation Organization) codes are four-letter identifiers used primarily by air traffic control, pilots, and airline operations. The first letter typically indicates the region (K for contiguous United States, E for Northern Europe, L for Southern Europe, etc.), and the remaining letters identify the specific airport. Examples include KJFK (New York JFK), EGLL (London Heathrow), KLAX (Los Angeles), and LFPG (Paris CDG). Unlike IATA codes, virtually every airport and airfield has an ICAO code.
Can I search for airports by city or country?
Yes! Our airport search supports multiple search methods. You can search by airport name (e.g., 'Heathrow'), city name (e.g., 'London'), IATA code (e.g., 'LHR'), or ICAO code (e.g., 'EGLL'). Results appear instantly as you type with at least 2 characters. We also provide browsing by country, continent, city, and timezone - making it easy to explore airports in any region of the world.
How accurate is the estimated flight time on distance pages?
The estimated flight time on our distance pages is calculated using an average commercial jet cruise speed of 850 km/h plus 30 minutes of overhead for taxi, takeoff, and landing. This provides a reasonable estimate for most commercial routes. Actual flight times may vary depending on wind conditions (headwinds or tailwinds), the specific aircraft type, air traffic routing, and weather. For the most precise flight duration based on your actual departure and arrival times, use our timezone-aware Flight Duration Calculator instead.
Why do arrival times sometimes appear before departure times?
This common confusion occurs due to timezone differences. When flying eastward (e.g., Los Angeles to New York), you 'lose' hours as you cross time zones, so a flight departing at 8:00 AM Pacific might arrive at 4:00 PM Eastern - an apparent 8-hour journey for a 5-hour flight. Conversely, flying westward 'gains' hours. Our flight duration calculator handles these timezone conversions automatically, showing you the actual duration regardless of how local times appear. You can also check the timezone difference between any two airports on their distance page.
What do the route classifications mean (short-haul, long-haul, etc.)?
Each airport distance page classifies the route based on distance: Regional (under 500 km) - typically operated by turboprop aircraft; Short-haul (500-1,500 km) - narrow-body jets like Boeing 737 or Airbus A320; Medium-haul (1,500-4,000 km) - narrow-body or wide-body aircraft; Long-haul (4,000-9,000 km) - wide-body aircraft like Boeing 777 or Airbus A350 with full meal service; Ultra-long-haul (over 9,000 km) - extended-range wide-body aircraft. This helps you understand what to expect on a given route.
Is this service free to use?
Yes, FlightDuration.online is completely free to use. You can calculate flight durations, check distances between airports, search our database of 30,000+ airports, browse by country or continent, and view detailed airport information - all without registration or payment. The service is powered by SharpAPI's airports database and maintained by A2Z WEB.
Can I find airports that don't have an IATA code?
Yes! While IATA codes are primarily assigned to commercial airports, our database includes thousands of airports and airfields that only have ICAO codes. These include military bases, private airfields, heliports, and smaller regional airports. In our search results, airports with IATA codes are displayed with a blue badge, while airports with only ICAO codes show an amber badge, making it easy to distinguish between them. Note that the distance calculator requires airports with IATA codes.
