Connection Designer

Test how a schedule change affects passenger connections before you publish it.

Connection Designer calculates which origin-and-destination markets a flight schedule connects, how alternative schedules differ, and which flight times perform best within defined operating constraints.

For airline and airport network planning, schedule planning, partnership teams, and aviation consultancies.

A schedule option and its connected markets, calculated from the selected sample week and connection rules.

One calculation path from schedule input to a reviewable result.

Every result is produced the same way: a composed sample week plus explicit connection rules, evaluated by one calculation, traceable down to individual flight rows.

01 · Data

Connect published schedules.

A configured global feed supplies a seven-day sample of the wider network — including flights operated by other airlines.

02 · Data

Load your schedule.

As an SSIM file, over a recurring SFTP feed, or through an agreed integration. Keep, remove, or replace carriers and services before the sample is created.

03 · Data · Optional

Attach market sizes and fares.

Weekly demand and representative fares add a passenger pool and a revenue pool to each OD market. Schedule data alone is enough for connection and market counts.

04 · Data · Managed

Self-service — or connected for you.

Each source can be configured by your own team. Or Leitmotif sets up and operates the connections — the published feed, the SSIM or SFTP delivery, and the market-data link — monitored and kept current, so the sample week is simply there when you need it.

05 · Calculation

Compose the sample week.

One composed sample plus explicit connection rules: MCT source, connection windows, airline and region filters, and circuity limits. Every tool reads from this same state.

06 · Tools

Analyse.

Test proposed flights against the sample and read the valid OD connections — grouped by flight, down to the inbound and outbound combination behind each one.

07 · Tools

Compare.

Two to five options against one baseline: markets gained, lost, improved, and declined, with the flights responsible for each difference.

08 · Tools

Partnership.

One trunk schedule between two hubs, each side with independent connection rules and its own market result.

09 · Optimization

Your scenarios — or the optimizer's.

Analyse, Compare, and Partnership run on schedules you enter by hand, or on schedules the optimizer generates: new rotations, retimes, or trunk timings, searched against a stated objective within explicit operating constraints. Always returned for review — never a silent overwrite.

10 · The whole path

Same sample, same rules, traceable results.

Three tools and one optimizer over a single calculation. A total can always be traced back to individual flight rows.

Compose a sample week from a published schedule, an uploaded schedule, or both; then apply filters before analysis.

Load data, compose the sample week.

Schedule data alone is enough for connection and market counts. Market sizes and fares are optional and add passenger and revenue pools to the same results.

Published schedules

A configured global feed supplies the wider network, including other airlines’ flights.

Your schedule

SSIM, SFTP, or an agreed integration — composed with the published feed, with carrier filters.

Market sizes and fares

Optional. Attaches a passenger pool and revenue pool to each OD market.

Sources can be self-service, or set up and operated by Leitmotif — configured, monitored, and kept current.

Analysis result: OD markets grouped by flight, with the underlying inbound and outbound services available for inspection.

Calculate what a proposed flight connects to.

Select flights from the loaded schedule or enter them manually. Set the hub, connection windows, MCT source, airline and region filters, and circuity limits — the result is the set of valid OD connections.

  • OD markets grouped by the proposed flight or rotation
  • The inbound and outbound combination behind each connection
  • Connection time, weekly frequency, and operating-day coverage
  • A parameter record, with detailed rows exported to Excel

If an arrival moves by 40 minutes, which markets become valid and which no longer connect?

OptimizationGenerate a new rotation, retime a rotation, or retime one leg — then recalculate.

Comparison result: each alternative is measured against Option 1, with market-level gains, losses, improvements, and declines.

Compare two to five options against one baseline.

Option 1 is the baseline. Alternatives can be edited schedules, different frequencies or operating days, partnership variants, or optimizer output.

  • Markets and connections gained or lost relative to Option 1
  • Connections that remain but improve or decline in timing or frequency
  • Weekly totals, day coverage, and average connection time per option
  • The flight combinations behind each market-level difference

How does a proposed bank retime compare with the current published schedule?

OptimizationCreate an optimized option beside the baseline, judged by the same measures.

Partnership result: one trunk variant, two independently configured hubs, and a separate market result for each side.

Test a trunk schedule across both ends of a partnership.

Two hubs joined by trunk rotations, each side with its own schedule version and connection rules. Every variant shows what it connects on both sides.

  • Independent windows, MCT source, filters, and circuity per hub
  • Several named trunk variants for the same case
  • Markets, weekly connections, and day coverage at each hub
  • The feeder and onward flights behind each trunk connection

Does a change that benefits one hub reduce connectivity at the other?

OptimizationGenerate trunk timings favoring one hub, the other, or a balanced result.

Bring one schedule question.

A useful first session starts with one sample week and one concrete case: a new route, a bank retime, an added frequency, or a trunk partnership. We will use the connection rules your team already applies and show the result down to the market and flight combination.
