A complete guide to the SN command in Amadeus โ how to display flight schedules between two cities, with options to search by departure time, arrival time, elapsed time, airline, or travel period.
Before you can book a flight, you need to know that it operates. Not every flight is available every day, and not every carrier serves every route. When a customer asks what flights operate between two cities, or when you are planning an itinerary and need to see the schedule rather than current availability, the SN command family is the correct tool. It displays scheduled flights between two cities, with options to search by departure time, arrival time, elapsed flying time, airline, or travel period. This guide walks through each SN variation with a working example and explains when to use it.
What Does the SN Command Do?
SN is the Amadeus GDS command used to display flight schedules between two cities.
Category: Schedule Display.
It displays scheduled flights between two cities, with options to search by departure time, arrival time, elapsed flying time, airline, or travel period.
Like the TN timetable command, SN is a planning tool rather than a booking tool. It shows you what operates on a route so you can advise the customer, plan an itinerary, or prepare to sell a segment later. Once you have chosen a flight, use SS from an availability display to sell it.
Neutral Schedule Display
Display the schedule from CDG to LHR on 19 October at 09:00:
SN19OCTCDGLHR0900This displays the scheduled flights from Paris Charles de Gaulle (CDG) to London Heathrow (LHR) on 19 October, starting from approximately 09:00. The neutral schedule shows all operating carriers on the route โ it does not filter by airline, class, or availability.
Use this format when the customer has a general question about which flights operate on a route, or when you are planning an itinerary and want to see all the options before choosing a carrier.
Schedule by Departure Time
Display the schedule based on a specific departure time:
SD19JUNMADLIS0800This displays the schedule from Madrid (MAD) to Lisbon (LIS) on 19 June for flights departing at approximately 08:00. The SD variation focuses specifically on departure times โ ideal when the customer has a preferred departure window.
Schedule by Arrival Time
Display the schedule based on a specific arrival time:
SA9FEBROMBOM1600This displays the schedule from Rome (ROM) to Mumbai (BOM) on 9 February for flights arriving at approximately 16:00. The SA variation focuses specifically on arrival times โ useful when the customer needs to be at a destination by a certain hour, or when there is an onward connection to consider.
Schedule by Elapsed Flying Time
Display the schedule based on elapsed flying time:
SE11NOVZRHGVA1400This displays the schedule from Zurich (ZRH) to Geneva (GVA) on 11 November for flights departing around 14:00, sorted or filtered by elapsed flying time. The SE variation is useful when the customer wants the shortest journey, or when you need to compare flight durations across different carriers on the same route.
Carrier-Preferred Schedule
Display a carrier-preferred schedule for the selected route:
SNAF13MAYPARLON0900This displays the schedule from Paris (PAR) to London (LON) on 13 May, starting from around 09:00, filtered for Air France (AF) as the preferred carrier. Use this format when the customer has a preferred airline, is a member of a specific loyalty programme, or is booking under a corporate agreement that requires a particular carrier.
7-Day Search
Display schedules using the 7-day search option:
SN/08FEBANCNOUThis displays the schedule from Anchorage (ANC) to Noumea (NOU) starting from 8 February, covering a seven-day window. The 7-day search is useful when you need to compare schedules across an entire week โ for example to identify which days a specific flight operates, or to find the best day for a customerโs travel plans.
Round-Trip Schedule
Display a round-trip schedule for the two travel dates:
SN23SEPCDGLHR*25SEPThis displays the schedule from CDG to LHR on 23 September, and the return from LHR to CDG on 25 September. Use the round-trip format when you want to see both legs of the journey at once โ helpful for planning a return trip and comparing outbound and inbound options side by side.
Dual-City Pair Schedule
Display schedules for a dual-city pair:
SN23SEPMADLIS*BCMCDGThis displays schedules for two city pairs at once โ Madrid to Lisbon and Bucharest to Paris โ on the same or related dates. Use this format when planning multi-city itineraries or comparing two unrelated routes for the same customer.
When to Use SN
Use SN when you need to view flight schedules rather than current seat availability, with different options for time, airline, dates, and city pairs. Typical scenarios include:
- Answering a customerโs question about which flights operate on a route.
- Planning an itinerary before opening an availability display.
- Identifying flights departing or arriving within a specific time window.
- Comparing flight durations across carriers on the same route.
- Finding the schedule for a preferred airline or loyalty programme.
- Checking what days a specific flight operates using the 7-day search.
- Comparing outbound and inbound options for a round-trip journey.
- Planning multi-city itineraries with a dual-city pair search.
How SN Fits Into Your PNR Management Workflow
A typical session using SN might look like this:
- Identify the route, date, and time window the customer is interested in.
- Choose the appropriate SN variation โ
SN,SD,SA, orSE, or use the carrier, 7-day, round-trip, or dual-city format. - Review the schedule and confirm the options with the customer.
- Check the flight details with DO if you need aircraft, terminal, or schedule verification.
- Display availability for the chosen flight and sell the segment with SS.
- Check the connection time with DM if the journey involves a transfer.
- Continue with pricing using FXP and save with ER or ET.
How SN Relates to Other Flight Information Commands
- SN / SD / SA / SE โ display flight schedules between two cities.
- TN / TD / TA / TE โ display flight timetables between two cities.
- DO โ displays detailed flight information for a specific flight, date, or segment.
- DM โ displays minimum connecting time for a connection.
- RTSVC โ displays flight service information for the flights in the current PNR.
- SS โ sells confirmed flight segments from availability.
- RTIM โ displays the full itinerary with married segment indicators.
The distinction between SN and TN is subtle. Both display scheduled flights, but SN offers the wider range of options โ carrier-preferred searches, 7-day windows, round-trip comparisons, and dual-city pair lookups โ while TN focuses on time-based variations. Use whichever matches the question you need to answer.
Important: A schedule display does not confirm seat availability or the ability to book a specific flight. A flight may appear on the schedule but be fully booked in the class the customer needs, or sold out entirely.
Schedules change seasonally โ airlines adjust routes for summer and winter periods, and services may be suspended or added. Always confirm the flight with DO or check availability before advising the customer or selling the segment.

Conclusion
The SN command family is the schedule display tool in Amadeus. Use SN19OCTCDGLHR0900 for a neutral schedule by route and date, SD19JUNMADLIS0800 when the customer has a preferred departure time, SA9FEBROMBOM1600 when they need to arrive by a specific hour, and SE11NOVZRHGVA1400 when flight duration matters. Use SNAF13MAYPARLON0900 to filter for a preferred carrier, SN/08FEBANCNOU for a 7-day comparison, SN23SEPCDGLHR*25SEP for a round-trip schedule, and SN23SEPMADLIS*BCMCDG for a dual-city pair search. Schedules are a planning tool โ they show what operates on a route, not what is available to book. Always confirm the flight with DO before advising the customer, especially for seasonal routes and long-haul flights. Paired with TN for timetable displays, DM for connecting times, RTSVC for flight services, SS for selling segments, and RTIM for itinerary review, the SN command completes your flight information toolkit and keeps every planning decision based on accurate schedule data.
