Most airline route planning tools are enterprise products sold by quote, so budget talks start with a sales conversation, not a public price list.
Amadeus Schedule Analytics and Cirium Diio suit teams that need market and schedule data first, while NetLine/Plan and Sabre focus more on building the network and the timetable itself.
Jeppesen and SITA-style flight planning tools answer a different question from network planning tools: they plan each flight, not the whole route network.
AeroCRS is the clearest option in this list for a small airline, because it combines scheduling, reservations and operations in one system.
Before you shortlist, fix your fleet size, your planning horizon and the data you already hold, because those three facts decide which tools fit.

How we choose
We reviewed vendor product pages and pricing pages on 2026-11-11 for each tool in this article, and we recorded whether a price was published or whether the vendor asked buyers to contact sales. We compared what each tool actually does: network modelling, schedule building, slot management, flight planning, market analytics, or small airline operations. We gave more weight to tools with a clear product page, named airline users, and a defined place in the planning workflow, and less weight to tools that only claim general aviation software with no detail. We did not claim hands-on testing, and we did not use third party price lists as a source for any price in this article. Where a vendor page showed no price, we wrote quote only and cited that vendor page in Sources.
Route planning in airlines covers two different jobs. One job is network planning: which cities to serve, how often to fly, and which aircraft to use. The other job is flight planning: the exact route, fuel and timing for one flight on one day. The tools below cover both jobs, and the notes under each tool make clear which job it serves. We reviewed vendor product pages and pricing pages on 2026-11-11, and every tool below either publishes no price or asks buyers to contact sales, so we list quote only where that is the case.

AAmadeus Schedule Analytics
Best for Market and schedule monitoring
Website: https://www.amadeus.com
Best for: Market and schedule monitoring
Starting price: quote only
Free plan: No
Pros: Weekly schedule updates; City pair capacity detail
Cons: No public price, so budgeting needs a sales quote
Amadeus Schedule Analytics gives network teams a single view of schedules and capacity across carriers, regions, countries, cities and airports, with updates each week. Planners can watch capacity and frequency changes, compare their own schedule with competitors, and spot changes to arrivals and departures that affect a route.
The tool draws on schedule data from full service and low cost carriers, and it reports aircraft type, operating days and available seat kilometres by city pair. That level of detail suits a planning team that needs evidence before it adds a frequency or opens a new city pair. The main limit is scope: this is an analytics and monitoring tool, not a schedule builder, so a team still needs a separate system to create and publish the timetable. Pricing is not published on the vendor page, so airlines must ask Amadeus for a quote based on data scope and users.

SSabre Network Planning and Optimization
Best for Schedule and slot management
Website: https://www.sabre.com
Best for: Schedule and slot management
Starting price: quote only
Free plan: No
Pros: Schedule Manager and Slot Manager in one suite; Used by large network carriers
Cons: No public price, and setup needs a formal commercial agreement
Sabre Network Planning and Optimization covers the practical work of turning a network plan into a published schedule. Schedule Manager helps airlines create, change and publish schedules based on market demand, operating limits and business goals. Slot Manager helps teams manage airport slot requests and allocations, which matters at congested airports where a good slot can decide if a route works. Air India and Singapore Airlines have used these tools for schedule and slot work, which shows the suite fits large network carriers.
The strength here is workflow depth rather than market data alone. Planners can work through schedule versions, keep slot records in order, and move from a draft timetable to a published one inside the same suite. The trade off is access: Sabre does not publish a price for this suite, and live use needs a commercial agreement, so a small airline should expect a long sales and contracting process. Teams that only need market research will find the suite heavier than they need.

LLufthansa Systems NetLine/Plan
Best for Long term network planning
Website: https://www.lhsystems.com
Best for: Long term network planning
Starting price: quote only
Free plan: No
Pros: Fast full network evaluation; Fleet assignment and hub design add-ons
Cons: No public price, and it is built for larger network carriers
NetLine/Plan is a network planning tool from Lufthansa Systems, developed with airlines over more than 20 years. It models passenger flows, costs and revenue for a whole network, and it can run a full origin and destination based network evaluation in less than 30 seconds, according to the vendor. Planners can simulate new connections, test timetable changes, and compare network options before they commit aircraft. Add-on modules cover fleet assignment and hub design, so the tool grows from a single route study to a full network plan.
JetBlue selected NetLine/Plan in 2025, becoming the first United States carrier to adopt it, and China Airlines also selected it in 2025. The product is delivered as a cloud hosted service through the vendor Global Aviation Cloud. The limit is fit: the tool is aimed at network carriers with complex hub and fleet choices, so a point to point carrier with a small fleet may find the depth more than it needs. No price is published, so buyers must request a quote.

IIBS Software iFlight
Best for Integrated flight and crew operations
Website: https://www.ibsplc.com
Best for: Integrated flight and crew operations
Starting price: quote only
Free plan: No
Pros: Flight operations and crew planning in one platform; Modular design for growing fleets
Cons: No public price, and network planning is only part of a wider operations suite
IBS Software iFlight is a digital platform for flight operations and crew management, rather than a pure network planning tool. It gives operations control centres live awareness of end to end flight operations, helps teams manage disruption, and supports crew pairing and rostering within policy and regulatory limits. The modular design lets an airline add functions as its fleet and network grow, and the vendor notes that Lynx Air implemented iFlight in four months, fully remote, with little custom work.
For route planning, iFlight matters because a network plan only works if operations and crew can deliver it. A route that looks good on paper can fail if crew pairings are costly or if turnaround times are tight, and iFlight lets planners test those limits. The con is focus: teams that want deep market modelling will need a separate analytics tool, because iFlight centres on operations and crew. Pricing is not published on the vendor product page.

JJeppesen Flight Planning and Dispatch
Best for Flight level route and fuel planning
Website: https://ww2.jeppesen.com
Best for: Flight level route and fuel planning
Starting price: quote only
Free plan: No
Pros: More than 30 years of airline flight planning experience; Fuel and time saving route optimisation
Cons: No public price for airline flight planning, buyers must contact sales
Jeppesen Flight Planning and Dispatch, from Boeing, plans individual flights rather than whole networks. It helps dispatch teams build flight plans that save fuel and time, reduce disruption risk, and improve on-time performance with routes tuned to wind, weather and aircraft performance. The vendor describes configurable, automated workflows and dedicated global service and support, including training, deployment and integration help at any hour.
This tool fits an airline that already has a network plan and needs to fly each route well. A dispatcher can compare route options, check alternates, and produce a plan that the crew can use. The limit is clear from the vendor page: it does not publish a price for airline flight planning, and buyers must contact sales to choose a plan. A network planner who needs market demand data will also need a separate analytics product, because Jeppesen centres on the flight itself.
7
CCirium Diio
Best for Airline market intelligence
Website: https://www.cirium.com
Best for: Airline market intelligence
Starting price: quote only
Free plan: No
Pros: Wide schedule, traffic and fares data; Scenario tools for network changes
Cons: No public price, and it is data and analytics rather than a schedule builder
Cirium Diio is an airline analytics platform that helps teams forecast travel trends with schedule, traffic and fares data. Diio Mi gives market intelligence for global airline and airport planning, while SRS Analyser and Diio Traffic and Fares add schedule, traffic and fare detail. Planners can benchmark a schedule, forecast demand, test network expansion ideas, and measure on-time performance, including for codeshare partners. Cirium also offers fleet data and a managed data warehouse, Cirium Sky, for teams that want to combine aviation data with their own records.
The value is evidence. A route case built on Cirium data can show market size, competitor capacity, fare patterns and connection flows, which makes it easier to defend a new route inside the airline. The limit is that Diio is an analytics platform, not a timetable builder, so planners still need a scheduling system to publish the plan. Cirium does not publish a price on its airline planning page, so buyers must request a quote.

OOAG Schedules Analyser
Best for Schedule based route analysis
Website: https://www.oag.com
Best for: Schedule based route analysis
Starting price: quote only
Free plan: No
Pros: Accurate global schedules data; Traffic, connections and mapper modules
Cons: No public price, and analysis needs care to turn into a published schedule
OAG Schedules Analyser helps airlines find commercial opportunities for new routes, spot aviation trends and watch competitor activity, using OAG schedules data. The traffic module lets teams study passenger demand and forecast traffic for new routes, while the connections module shows possible global connections for all airlines and plots them on a map. A mapper module turns plans and projections into route maps, and a United States Department of Transportation module gives access to United States airline data for cost and performance comparison.
OAG describes its schedules data as spanning from 1996 to 12 months ahead in its newer Analyser+ platform, with more than 150 dimensions and 14 metrics for schedule, capacity and frequency work. That history helps a planner test if a route has held up across seasons and market cycles. The limit is the same as with other analytics tools: analysis is not the same as building and publishing a schedule, so a separate scheduling tool is still needed. OAG does not publish a price on the pages we reviewed.

AAeroCRS
Best for Small airline scheduling and reservations
Website: https://www.aerocrs.com
Best for: Small airline scheduling and reservations
Starting price: quote only
Free plan: No
Pros: Scheduling, reservations and operations in one cloud system; Fast setup for small airlines
Cons: No public price on the vendor site, and it suits small fleets rather than large hubs
AeroCRS is a cloud system for small airlines, low cost carriers, charter operators and regional carriers. It covers scheduling, reservations, customer records, agency management, departure control and distribution, so a small team can plan routes, sell seats and run the day of operation from one place. The vendor says airlines can go live within a day, with a short training process, which is a sharp contrast to the months long setup common with enterprise network planning suites.
For route planning, AeroCRS fits teams that need a workable schedule and a booking engine together, rather than deep market modelling. A planner can create a timetable, set fares and classes, manage inventory in real time, and connect to distribution partners. The limit is scale: the product is built for small and medium fleets, so a large hub carrier with complex crew, slot and codeshare needs will outgrow it. The vendor does not publish a price, so buyers must contact AeroCRS for a quote.
What to check before you buy
Start with the planning question you need to answer. If the question is which markets to serve, you need market and schedule data from a tool like Amadeus Schedule Analytics, Cirium Diio or OAG Schedules Analyser. If the question is how to build and publish the timetable, you need a scheduling tool like Sabre Schedule Manager or NetLine/Sched, with NetLine/Plan for the network case behind it. If the question is how to fly each route at low fuel cost, you need flight planning from Jeppesen. Mixing these jobs in one shortlist leads to a poor choice, because a good analytics tool will not publish a timetable.
Check data coverage next. Ask each vendor which carriers, regions and time periods its schedule and traffic data cover, how often the data updates, and whether your own booking and cost data can feed the model. Ask for a sample output for two routes you know well, one strong route and one weak route, and see if the tool explains the difference in a way your team trusts.
Check integration and setup time. Enterprise tools often need months of setup, data work and training, while AeroCRS can go live much faster for a small fleet. Ask for a written setup plan with dates, data needs, training hours and support hours, and ask who on your team must supply schedule, fleet and cost data. Confirm how slots, codeshare schedules and crew rules flow into the tool, because a plan that ignores those limits will fail in operation.
Use this decision table to narrow the list before you ask for quotes.
FAQ
What is the best airline route planning software for a small airline?
AeroCRS is the clearest starting point for a small airline, because it combines scheduling, reservations and operations in one cloud system and can go live fast. Larger tools in this list are built for network carriers and carry enterprise pricing and setup. A small team should still check market data from OAG or Cirium before it commits to a new route.
How much does airline route planning software cost?
Most tools in this article are quote only, because vendors price by fleet size, data scope, users and modules. Only a sales quote can give a real number for your airline. Expect enterprise tools to cost far more than small airline systems, and ask each vendor for setup fees, annual fees and data fees in writing before you sign.
Is there a free plan for airline route planning software?
No tool in this list offers a free plan for airline route planning. Enterprise tools are sold by quote with no free tier, and even AeroCRS is a commercial product. Some vendors offer a demo or a trial for related products, so ask for a guided demo with your own routes rather than expecting a free account.
What is the difference between network planning and flight planning?
Network planning decides which cities to serve, how often to fly and which aircraft to use, using demand, cost and competitor data. Flight planning decides the exact route, altitude, fuel and timing for one flight on one day. Both matter, but they need different tools, so shortlist network tools and flight planning tools as separate choices.
Can one tool cover network planning, scheduling and flight planning?
No single tool in this list covers all three jobs well. NetLine covers network and schedule work, Sabre covers schedule and slot work, and Jeppesen covers flight planning. Most large airlines combine two or three tools, with market data from Cirium or OAG. A small airline can cover more ground with AeroCRS, but it will still need market data for big route decisions.
