Diversion management that picks the right airport, lines up the ground and puts every cost on the record
Diverted flights back on their way the same day, with every cost on the record.
See one case, screen by screen ↓Diversion management is how an airline's operations control center chooses a diversion airport and recovers the flight: handling, fuel, customs, passengers, crew legality, the tarmac clock and the cost. Flight Diversion Management adds eight agents that rank the airports with every fact cited and draft each recovery action in parallel, while the dispatcher and duty manager approve every action and sign the decision.

Diversion management starts the moment a crew sends the ACARS downlink: a passenger with chest pain, a technical fault, weather at the destination — one of the costliest irregular operations an operations control center runs. The aircraft dispatcher and the captain have minutes to choose an airport, and the dispatcher checks each candidate by hand across flight planning, METAR and TAF, NOTAMs, the company's airport suitability list, fire category, runway length against landing weight and customs hours. Then the operations control center spends the next hour on the phone — the handler, fuel, an ambulance, customs, an APIS manifest for the flight on to the US, hotel rooms, crew legality and rebooking.
The cost is decided in that hour. The closest airport is not always the suitable one. A fuel order written for an overweight landing contradicts the captain's plan to jettison. A crew that times out on the ground turns a two-hour stop into an overnight, while the tarmac clock runs. Weeks later finance rebuilds what the diversion cost from email and invoices.
Estimated split of staff working days for one long-haul diversion, from the declaration to a closed cost record and filed reports, by hand and with the solution.
Eight agents rank the airports and line up the ground in parallel; the dispatcher and duty manager approve every action.
Thursday, October 15, 2026. Corvane CV 96, London Heathrow to Denver, a Boeing 787-9 with 216 passengers, is at FL380 over Hudson Bay when a 64-year-old passenger has severe chest pain. Here is what happens next, screen by screen, in the working solution.
Marcus shares operational control of 22 long-haul flights on the international desk. Today shows 412 Corvane flights airborne, 6 watched for diversion risk, and CV 96 at the top: declared at 18:04Z by the crew, six airports ranked at 18:06Z, YWG Winnipeg recommended. Below it, what the agents found since 06:00Z and the three items waiting for him.
“The recovery is already prepared for Winnipeg and starts when you choose.”
CV 96 sits at the center of 30, 60 and 90-minute rings at 487 knots. The planner read the ground medical advisor's note, six airport records, METAR and TAF, 14 NOTAMs and N809CV's limits, and ranked on medical priority. YWG Winnipeg is 69 minutes away with an 11,000 ft runway, fire category 9, CBSA customs 24 hours, a handler on call, 1,900 hotel rooms and the crew legal to continue.
“YWG Winnipeg first. The one reason it beat YQT Thunder Bay: the patient reaches cardiac care 17 minutes sooner — 90 against 107 minutes.”
YYQ Churchill is 143 nm and 24 minutes away. Its record says why it is off the list for this emergency: fire category 5, below the 787-9's minimum of 7; a health center with no cardiac care, so a medevac to Winnipeg of about 2 h 40; no widebody stairs or tow bar; 160 rooms in town for 214 passengers. Each fact opens its source.
The Diversion Planner never chooses the airport — the dispatcher and the captain decide.
The Cockpit Messenger drafts the uplink. The Station & Fuel Coordinator lines up handling, paramedics, customs, catering and fuel at YWG — 5 requests. The Passenger Care agent holds hotels and writes the message to passengers, and the Crew Legality agent checks 12 crew members and finds reserve crew R-07 at ORD. Six steps in 3.8 seconds end with 10 drafts waiting for 4 people.
“Working in parallel on YWG. Each action below is a draft until its owner approves it.”
Marcus sends the uplink, and the captain replies that she will jettison 32,000 lb to land at 424,300 lb, below maximum landing weight. The Checker sees that the fuel order assumed an overweight landing with 50,500 lb on board, changes the uplift from 6,000 lb to 38,000 lb (5,672 US gal) and sends it back to Renée Castellano to approve again. The overweight-landing inspection is no longer needed.
The Checker can block a draft, never approve one.
The cockpit thread holds every ACARS message with the crew of CV 96: the declaration, the dispatcher's uplink with runway, weather, fire category and the landing-weight note, and the captain's reply. Marcus records Capt. Elena Brandt's decision — divert to YWG and jettison 32,000 lb — with the ACARS message as evidence. The next uplink is already drafted, waiting for him.
The Cockpit Messenger never sends without the dispatcher, and never argues with the captain's emergency authority.
216 on board, 214 continuing, 47 connecting at Denver and 11 who will miss their connection, with rebooking ready. Six need assistance. The Passenger Care agent holds 138 rooms for 214 passengers at two hotels as a fallback, free cancellation until 22:00Z, and drafts the message in English, Spanish and German. Under UK261, an arrival 86 minutes late is under the 3-hour threshold and the cause is a medical emergency on board: no compensation, refreshments owed.
The Passenger Care agent holds rooms only with free cancellation, and sends no message without approval.
Every crew member's duty sits on one timeline against their limit. The pilots' limit is 15 hours, not 17, because the crew-rest compartment is deferred under MEL 25-50-01 — and they still reach Denver with 2 h 49 to spare. The flight attendants have 7 h 34. Reserve crew R-07 is held at ORD, not called, with a call-by of 19:45Z.
The Crew Legality agent never calls a reserve and never plans on a 117.19 duty extension.
The Continuation Advisor compares three options. Continuing with the same crew lands in Denver at 23:31Z, 86 minutes late, with 11 misconnections all rebooked and every clock met. Swapping to R-07 costs $14,800 more and arrives 3 h 20 late; canceling and overnighting at YWG costs $214,638 and cancels tonight's CV 97 to London. Renée signs the recommended option with the reason “Crew legal and aircraft serviceable”.
The Continuation Advisor recommends only — the duty manager signs.
Ten lines, each tied to the action that caused it: landing and terminal fees $5,420, ad-hoc handling $11,800, the 38,000 lb fuel uplift $20,533, fuel jettisoned $12,943, crew pay and per diem $3,180, and the 138 hotel rooms held at no cost. The total is $61,338, against a typical $95,000 for a long-haul widebody. The close-out shows the decision signed and the captain's decision recorded; the duty manager sends it to operations finance from the same screen.
“Invoices are matched to these lines as they arrive — the Cost Recorder flags any line that moves more than 5%.”
The same diversion, seen by four of the people who carry it — what that hour looked like, and what it looks like now.
Eight agents rank the airports and line up the ground in parallel; the dispatcher and duty manager approve every action.
Ranks candidate airports on the range rings for the event type — runway at landing weight, fire category, customs, handling, stairs, fuel, medical access, hotels, weather, NOTAMs and crew legality — and opens with its top choice and the one reason it beat the second.
Drafts ACARS uplinks in company style — airport, runway, weather, fire category, landing-weight note, stand — and reads each downlink, telling the other agents what the crew decided.
Requests handling, stand, paramedics, customs, the APIS manifest, fuel and catering at the diversion airport, tracks the replies and escalates.
Holds hotel rooms as a fallback, writes the message to passengers, rebooks missed connections and works out what passengers are owed under UK261, EU261, the DOT tarmac rule and Canadian passenger rules.
Checks every crew member against Part 117 and 121.467 for the continuation, with deferred items that change a limit, and lines up a recovery crew.
Compares continue, swap crew and cancel on cost, crew, passengers and clocks, and says when its recommendation would change.
Re-computes every number across the drafts against aircraft limits and deferred items, and sends conflicts back to the agent that wrote them with the reason.
Writes the cost record as actions happen, from tariffs, rate cards, fuel prices and crew pay rules, and matches invoices when they arrive.
Choose the airport, approve each action, sign the decision. The agents propose; a named person decides.
Ask in plain words — or say what to change. Every answer points to its source, and the screen follows the answer.
Why is Winnipeg ranked above Thunder Bay?
On medical priority the lead factor is time to cardiac care: 90 minutes at YWG against 107 at YQT. YQT also has no widebody stairs until Oct 21 and a 7,318 ft runway against 11,000. Both keep the crew legal. I opened the comparison.
Is the crew still legal if we stay on the ground 4 hours?
Yes, just: with 4 hours at YWG the pilots reach Denver at 01:21Z, 59 minutes inside their 02:20Z limit. At 5 hours they would be out by 1 minute. Over 3 hours, passengers must be offered deplaning. I set the timeline to 4 hours.
Hold rooms for the crew as well
Done as a draft: 12 rooms for the 3 pilots and 9 flight attendants at the Prairie Gate Hotel, crew rate $119, same free cancellation until 22:00Z. It is added to the hotel hold waiting for Renée.
What has the CV 96 diversion cost so far?
$61,338 across 10 lines: fuel uplift $20,533, fuel jettisoned $12,943, handling $11,800 and fees $5,420 are the biggest. A typical long-haul widebody diversion costs about $95,000.

Diversion management is how an airline's operations control center chooses a diversion airport and recovers the flight: handling, fuel, customs, passengers, crew legality, the tarmac clock and the cost. Flight Diversion Management adds eight agents that rank the airports with every fact cited and draft each recovery action in parallel, while the dispatcher and duty manager approve every action and sign the decision.
The dispatcher and the captain decide together. The Diversion Planner ranks every candidate within reach on 30, 60 and 90-minute rings using the priority for the event — for a medical diversion, time to cardiac care — and checks runway length at landing weight, fire category, customs, handling, stairs, hotels, weather, NOTAMs and crew legality. It names its top choice and the one reason it beat the second, and shows unsuitable airports with the reason.
EUROCONTROL puts a typical intercontinental widebody diversion at €82,000, about $95,000, and MedAire puts medical diversions at $15,000 to $200,000 each. In the working solution the sample medical diversion's cost record comes to $61,338 across 10 lines, written as each cost happened and matched to invoices as they arrive.
Under 14 CFR 259.4, a carrier must provide food and water no later than 2 hours after a tarmac delay begins, and offer passengers the chance to deplane before the delay reaches 3 hours on a domestic flight or 4 hours on an international one. The solution keeps these clocks live for each diversion — in the sample, the Canadian 3-hour rule at Winnipeg — with a food and water target of 1 h 45 by default, and tells the owner before a clock runs out.
The Crew Legality agent checks every crew member against Part 117 and 121.467 for the continuation, including deferred items that change a limit, and shows the margin in hours and minutes. It lines up a recovery crew but never calls a reserve and never plans on a 117.19 duty extension; the crew controller decides.
Yes. The agents never choose the airport, send to the cockpit, approve any spend, call a reserve or sign. Every outward action is a draft until its named owner approves it, the captain's decision is recorded under 14 CFR 121.557(b), and the duty manager signs continue, swap or cancel with a reason.
It connects to flight planning and flight following, ACARS datalink, the weather and NOTAM feed, crew tracking, maintenance deferred items, reservations and departure control, hotel booking, fuel ordering and finance, and keeps your diversion airport records current from NOTAMs and station email, with each change confirmed by station operations.
