ILIAMNA Independent flight intelligence

Not an airline, operator, broker, or booking service.

Airport field desk

Make the airport part work.

The layover number is only the shell. Find the boundary that changes the work, then inspect the exact airport, operating carrier, ticket, bag, border, and clock.

The boundary scan

Six questions before you trust the clock.

These are inspection layers, not a universal airport sequence. Use only the layers that apply, and verify each one with the current operating carrier, airport, and relevant authority.

  1. Layer / Ticket

    Who issued it, and who operates it?

    Record whether the flights share a reservation and issued ticket. Then identify the operating carrier for each flight and who says they will recover a missed handoff.

    Inspect ticket structure →
  2. Layer / Bag

    Where does the checked bag stop?

    Read the tag and current carrier instructions. Through-checking, border collection, separate tickets, and an airport change can alter the reclaim and acceptance work.

    Trace the bag →
  3. Layer / Border

    Which authority decides the next step?

    Transit, entry, immigration, and customs work can depend on the jurisdiction and traveler. Use the current official instructions for the exact journey.

    Start with primary sources →
  4. Layer / Security

    Do you stay inside the same controlled area?

    Do not infer the answer from the terminal name. Ask whether this itinerary requires an exit, another screening step, or a route that is unavailable to your arrival.

    Put the task in the buffer →
  5. Layer / Place

    Gate, concourse, terminal, or another airport?

    Name the movement precisely. An airport change adds a landside journey plus new-airport acceptance and security work.

    Audit both deadlines →
  6. Layer / Clock

    Which deadline closes first?

    Separate scheduled departure, current carrier cutoffs, airport instructions, a location-specific published minimum, your task workload, and your own contingency.

    Build the whole clock →

Possible work, not a route map

Write the chain in verbs.

A Heathrow self-connection example can include immigration, bag collection, a landside terminal move, check-in, security, and gate travel. That is a local example, not a sequence to copy elsewhere.

  2. 02Crossborder or security boundary, if required
  3. 03Collectchecked bag, only when instructed

Choose the next move

Use the guide that matches the handoff.

Every destination below already exists. The tools calculate only from values you enter, keep missing evidence visible, and do not send your planning fields to Iliamna.

One connection, one airport

Expose the work inside the layover.

Start with the published airport and carrier evidence, then add the border, bag, security, terminal, and personal contingency layers.

Build a connection buffer → One connection, two airports

Put the road inside the clock.

Audit the arrival-side deadline and the onward gate deadline without a live traffic claim or a default transfer time.

Audit an airport change → The whole journey

Connect the front door to the final stop.

Keep positioning, airport work, flight time, arrival tasks, and onward ground travel on one visible ledger.

Plan door to door → Ticket structure

Find who owns each handoff.

Separate the itinerary display, issued ticket, operating carrier, baggage arrangement, and disruption responsibility.

Map the ticket → Checked baggage

Follow the tag, not the assumption.

Record the tag destination, border collection, reclaim, recheck, and airport-change work before treating the bag as transferred.

Trace the bag handoff → A broken chain

Capture the facts before buying again.

Build a compact evidence card for the ticket, operating carrier, actual offer, bag location, airport work, and event times.

Open the recovery guide →

Evidence discipline

Airport examples stay local.

Heathrow and Gatwick illustrate how much work one connection can contain. They do not establish a rule for another airport. IATA describes a minimum connecting time as location-specific, which is why Iliamna does not invent one.

Recheck the current airport, operating carrier, and relevant authority before travel. Rules and processes can change.
