Airline disruption management on one storm evening at DEN
Thursday, October 15, 16:22 MDT at the Denver hub of Corvane Airways. A line of thunderstorms is coming, and 188 flights, 28,289 passengers and 2,540 connections are at risk in the 16:00, 17:30 and 19:00 banks. Here is what happens next, screen by screen, in the working solution.
- 0116:21
The agents speak first: “I have three plans.”
Dana Whitfield · Duty ManagerDana's Today screen opens on a message from the Recovery agent: “Ground stop likely at 16:40. I have three plans.” Since 15:41 the agents have read 9 feeds, built 11 recovery plans and rehearsed every one. Plan B cancels 14 short flights, swaps a healthy 787 onto London and keeps 2,262 of 2,540 connections for $1.81M. Under “Needs you”: nothing has gone to stations, crews or customers yet, two aircraft are in the departure queue, and one swap waits for maintenance control.
“One decision needs you before 16:40.”
- 02How sure is it?
An early warning with its confidence and its sources
Watch agentThe Watch agent read convective SIGMET 47C — a line 40 nm wide moving east at 25 kt, tops FL450 — the DEN TAF amendment, lightning within 5 nm and FAA advisory 112, which calls a ground stop probable from 16:40 with a ground delay program likely after. Confidence rose from 0.74 to 0.82. A what-if tries the ground stop at 16:30 or 17:00 to show how sensitive the plans are; it never changes them.
The Watch agent warns and cites; it never declares an event.
- 03The recovery
The hub's banks, the storm and three plans, side by side
Recovery agentThe Recovery screen draws the DEN day as arrival and departure bank waves from 12:00 to 23:00, with the thunderstorm line from 16:30 to 19:00, the likely ground stop from 16:40 to 18:30 and the ramp closed for lightning from 16:35 to 17:45. Plan A holds and delays for $2.61M with 9 crew time-outs; Plan B thins the 17:30 bank for $1.81M; Plan C cancels early for $2.05M. Each plan is drawn over the real schedule, with its cost receipt below.
“I built 11 plans and rehearsed each against crew duty limits, MEL items, curfews, connections and the DOT tarmac rule; three passed. I recommend Plan B.”
- 04Rehearsal
Eight plans failed, and she can see why
Four checking agentsThe crew legality, aircraft and MEL, connections and obligations agents rehearse every plan without seeing the planner's reasoning. Plan D kept N806CV on CV 118 to London, but MEL 49-11-01 (APU inoperative) limits it to ETOPS 120 minutes and the route needs ETOPS 180. Plan G would land CV 1187 at Santa Ana at 23:24, after the 23:00 curfew. Plan H would take CV 1206 to its 3-hour tarmac limit at 19:05. None of the eight is ever offered as an option.
“8 plans failed rehearsal — never shown as options; here so you can see what was tried.”
- 05One sentence
“Keep CV 418, cancel CV 412 instead”
Dana Whitfield · Duty ManagerPlan B as proposed cancels CV 418 to Chicago. Dana knows Chicago matters more tonight and types the change. The Recovery agent re-solves Plan B in 8.2 seconds and the four checks run again: still 14 cancellations, connections kept 2,262 → 2,310 (+48), cost $1.81M → $1.84M (+$30,000). CV 418 carries 96 connecting passengers to Chicago, CV 412 carries 48. She accepts the edit with reason E1 · Customer priority.
Nothing changes until she presses “Accept the edit”; “Undo” puts Plan B back as proposed.
- 0616:27
“Why not delay CV 412?” — answered with the rule
Crew legality agentCaptain Henrik Dahl and First Officer Maya Collins reported at 07:05 and CV 412 is their fourth segment, so Part 117 Table B allows 13 hours and their duty ends at 20:05. The earliest slot is 19:10, block-in 21:15 — a 1 h 10 min extension. The captain took a 52-minute extension on Tuesday with no 30-hour rest since, so a second one over 30 minutes is not allowed, and no reserve A321neo captain is at DEN before 21:40.
“Canceling and rebooking its 142 passengers costs $41,000 less than a reserve-crew delay after 22:00.”
- 07The London swap
A healthy 787 for London, confirmed by maintenance control
Aircraft and MEL agent · Grace LindqvistN806CV's APU has been inoperative since Oct 14 at 21:12, a category C item under MEL 49-11-01, which limits it to ETOPS 120 minutes. N812CV came in from SFO at 16:05 with no open items and takes CV 118 to London at 20:05; N806CV flies the domestic CV 1772 to Houston, where ground power and air are confirmed. Grace Lindqvist, maintenance control, confirmed both swaps at 16:20.
The Aircraft and MEL agent never clears an MEL item and never confirms a swap; maintenance control does.
- 08The clocks
Every tarmac, refund and curfew clock in view
Obligations agentCV 1206 closed its door at 16:05 and CV 1318 at 16:12, so their 3-hour domestic tarmac limits fall at 19:05 and 19:12. Plan B returns both to the gate by 17:12. The obligations agent warns at 2 h 15 min, starts returns by 2 h 30 min, and keeps the refund queue under the DOT automatic refund rule. In Plan A, four flights would have come within 30 minutes of the limit.
The obligations agent never waives an obligation and never sends a refund.
- 0916:31 · signed
She signs with a reason code; only then does anything move
Dana Whitfield · Duty ManagerThe signing screen restates the plan — 14 cancellations, 22 delays, 4 swaps, 2,310 of 2,540 connections kept, $1.84M, all five checks passed — and what will be sent. The plan is under the co-sign limits of 25 cancellations and $3M, so her signature is enough. She picks S2 · Protects connections and customers and signs as Dana Whitfield, Duty Manager, at 16:31 MDT.
“When you sign, the release agent sends the plan to 8 stations, dispatch, ATC, 31 crew members and 5,072 passengers, and tracks every acknowledgment.”
- 10The release
Everyone who acts on the plan is told, and every acknowledgment is tracked
Release agentCancellation and gate notices go to 8 stations, 22 amended releases to dispatch for Marcus Bell to sign, 9 slot substitutions from the canceled DEN arrivals, new reports and hotels for 31 crew members, messages to 1,964 passengers on canceled flights and 3,108 on delayed ones, and 410 rooms at six contracted DEN hotels. Each has a time limit and an owner; OMA station is flagged as overdue at 7 of 8.
The release agent never sends before signature; the dispatcher signs every amended release.
